TMPO is only used by arch/x86/Makefile.
Change arch/x86/Makefile to use $$TMPO.o and remove TMPO from
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.
