Both tools are used unconditionally by images/Makefile.mxs. Always
build them for ARCH_MXS, and remove their prompt in the host tools
section, as they are not really useful as stand-alone tools.

On ARM, .word is 32-bit as expected in the script, but on x86 it's
16-bit, which leads to truncation.
.int on the other hand is 32-bit both on ARM and x86 and very likely
all other platforms we support, so change the .word to .int.

While buf == _buf, their type and sizeof differ. The read syscall should
have the buffer size as argument, but instead got the pointer's size.
This likely doesn't change high-level behavior, because read was called
in a loop, so fix this.

This corresponds to Linux commit 7e2521a85c98 (that currently sits in
linux-next) with the same short log.
When building with
$ HOST_EXTRACFLAGS=-g make
the expectation is that host tools are built with debug informations.
This however doesn't happen if the Makefile assigns a new value to the
HOST_EXTRACFLAGS instead of appending to it. So use += instead of := for
the first assignment.

Introduce a new variable to store a buildsystem version information.
The exact information that is stored here (git commit, git tag,...) is
defined by the buildsystem.
It is intended to have the possibility to get information about the
exact barebox binary, environment and configuration.
The variable is utilized the same as KERNELVERSION for linux:
make BUILDSYSTEM_VERSION=$COMMITISH
Via scripts/mkcompile_h this information is injected into the barebox
codebase.

Coccinelle detected that bootfrom and nandeccmode are unsigned, but
check to be less than zero. Both are only used to hold the return value
of functions that either return up to 0xFF on success and a negative
error code otherwise. It's thus safe to make them signed. Do so.

KernelAddressSANitizer (KASAN) is a dynamic memory error detector. It
provides a fast and comprehensive solution for finding use-after-free
and out-of-bounds bugs.
This adds support for KASan to barebox. It is basically a stripped down
version taken from the Linux Kernel as of v5.9-rc1.
Quoting the initial Linux commit 0b24becc810d ("kasan: add kernel address
sanitizer infrastructure") describes what KASan does:
| KASAN uses compile-time instrumentation for checking every memory access,
| therefore GCC > v4.9.2 required. v4.9.2 almost works, but has issues with
| putting symbol aliases into the wrong section, which breaks kasan
| instrumentation of globals.
|
| Basic idea:
|
| The main idea of KASAN is to use shadow memory to record whether each byte
| of memory is safe to access or not, and use compiler's instrumentation to
| check the shadow memory on each memory access.
|
| Address sanitizer uses 1/8 of the memory addressable in kernel for shadow
| memory and uses direct mapping with a scale and offset to translate a
| memory address to its corresponding shadow address.
|
| For every 8 bytes there is one corresponding byte of shadow memory.
| The following encoding used for each shadow byte: 0 means that all 8 bytes
| of the corresponding memory region are valid for access; k (1 <= k <= 7)
| means that the first k bytes are valid for access, and other (8 - k) bytes
| are not; Any negative value indicates that the entire 8-bytes are
| inaccessible. Different negative values used to distinguish between
| different kinds of inaccessible memory (redzones, freed memory) (see
| mm/kasan/kasan.h).
|
| To be able to detect accesses to bad memory we need a special compiler.
| Such compiler inserts a specific function calls (__asan_load*(addr),
| __asan_store*(addr)) before each memory access of size 1, 2, 4, 8 or 16.
|
| These functions check whether memory region is valid to access or not by
| checking corresponding shadow memory. If access is not valid an error
| printed.

Use 'userprogs' syntax to build standalone programs for the target
architecture (i.e. the same architecture as the barebox).
This changes the compiler flags passed to the target programs.
Previously, it used $(KBUILD_CFLAGS), which contains the same compiler
flags as used for the barebox space.
Going forward, it will use $(KBUILD_USERCFLAGS), which contains smaller
set of compiler flags because there is no need to add low-level options
for userspace builds.
The shortlog will be annotated with [U].

When we have written the barebox header the next thing we do is to lseek
forward by the size of the header gap. This means our position is
already inside of the rest of the image and we have to skip this offset
from the rest of the image. This only works when the rest of the image
doesn't have anything needed in the first few bytes. Some newer SoCs
have the IVT at offset 0 though, so with the current approach we skip
writing the IVT.
Instead of doing this we should lseek to the end of the header gap.
With this we are at the right position to just write the full image
containing the IVT.

Starting v4.13, Linux always uses thin archive instead of relocatable
ELF to combine builtin objects.
The thin archive is basically a text file that only contains paths to
object files.
As Linux commit 98ced886dd79 mentioned, this has a lot of benefits:
- save disk space for builds
- speed-up building a little
- fix some issues when liking a giant executable (for example,
allyesconfig on ARM Linux)
- work better with dead code elimination
The last one is important for barebox because pbl highly relies on the
dead code elimination (-f{function,data}-sections and --gc-sections)
dropping symbols that are unreachable from the linker's entry point.
The dead code elimination does not work if the same symbol names are
used in the pevious incremental link mechanism because the same name
symbols all go into the same section.
Commit a83c97f2a406 ("ARM: socfpga: generate smaller images when
multiple boards are selected") worked around it by giving a dedicate
section to each of the same name symbols. This workaround can go away.
built-in.o was renamed to built-in.a since it is now an archive.
built-in-pbl.o was renamed to built-in.pbl.a for consistency.

The current Linux uses the unified build command for built-in objects
and module objects. This is possible because part-of-module is set to
y when the target is being built for a module. If so, quiet_modtag is
set to [M], and modkern_cflags is set to KBUILD_CFLAGS_MODULE instead
of KBUILD_CFLAGS_KERNEL.
Currently, barebox uses a separate build command for pbl, but the
difference between cmd_cc_o_c and cmd_pbl_cc_o_c is just
"-D__PBL__ $(PBL_CPPFLAGS)".
By using the same approach as Linux, they can be unified.
Set part-of-pbl flag to y when the target is being built for pbl.
Merge cmd_as_o_S and cmd_link_o_target as well.
This also changes the shortlog style as follows:
PBLCC -> CC [P]
PBLAS -> AS [P]
PBLLD -> LD [P]
This is more consistent with the policy in the Linux build system.
In Linux, a capital letter enclosed square blackets indicates which
target the object is being built for.
CC object built for built-in
CC [M] object built for modules
CC [U] object built for userspace (proposed for Linux 5.8-rc1)
The idea behind this is we use the same compiler $(CC) for them.
Only the difference is the compiler flags. On the other hand, host
programs are compiled by a different tool, $(HOSTCC), hence the
shortlog is 'HOSTCC'.
Barebox supports module builds (it seems), but the [P] notation does
not conflict with [M] because pbl has a limited memory footprint.
We never expect pbl can support the module feature.
