The method for getting a memory usage report printed during build, is based on a GNU linker (ld) option flag, and thus is not necessarily supported by other toolchain binary tools. The introduced cmake macro allows for a given toolchain to specify how the memory usage report is to be generated, and whether the command for generation, if any, is to be added to the post_build_commands and the post_build_byproducts lists of the top level CMakeLists.txt The intent here is to abstract Zephyr's dependence on toolchains, thus allowing for easier porting to other, perhaps commercial, toolchains and/or usecases. No functional change expected. Signed-off-by: Danny Oerndrup <daor@demant.com>
