kbuild: split cc-option and friends to scripts/Makefile.compiler scripts/Kbuild.include is included everywhere, but macros such as cc-option are needed by build targets only. For example, when 'make clean' traverses the tree, it does not need to evaluate $(call cc-option,). Split cc-option, ld-option, etc. to scripts/Makefile.compiler, which is only included from the top Makefile and scripts/Makefile.build. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

kbuild: set EXIT trap before creating temporary directory Swap the order of 'mkdir' and 'trap' just in case the subshell is interrupted between 'mkdir' and 'trap' although the effect might be subtle. This does not intend to make the cleanup perfect. There are more cases that miss to remove the tmp directory, for example: - When interrupted, dash does not invoke the EXIT trap (bash does) - 'rm' command might be interrupted before removing the directory I am not addressing all the cases since the tmp directory is harmless after all.

Makefile.compiler: replace cc-ifversion with compiler-specific macros cc-ifversion is GCC specific. Replace it with compiler specific variants. Update the users of cc-ifversion to use these new macros.
