make: Add bbenv-y target to generate default environment files

This adds a target to generate environment files from directories.
These are compiled into the barebox binary.

use it as:

bbenv-$(CONFIG_SOMETHING) += my-environment

The directory containing the files to compile into the binary
should be named my-environment.

This can be accessed in C code later as:

extern unsigned char __bbenv_my_environment_start[];
extern unsigned char __bbenv_my_environment_end[];
