cmake: Toolchain abstraction: Introducing macro toolchain_cc_nocommon The macro is intended to abstract the -fno-common compiler option which controls the placement of uninitialized global variables. The macro leaves it up to the toolchain to define the option. 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.

cmake: Toolchain abstraction: Abstract compiler flag for add debug info The macro, toolchain_cc_produce_debug_info, adds the compiler specific flag for enabling the production of debugging information in the toolchain native format. 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.
