Subject: [PATCH] Fix build with EABI toolchain

When using an EABI toolchain, the default compilation generates
references to __aeabi_unwind_cpp_pr0(). This symbol is defined in
libgcc, but we don't want to use it for a bootloader.

Therefore, this patch passes some additional CFLAGS to disable the
generation of such references by avoiding unwind tables, exceptions,
etc.
