Adding support to remove options from final CFLAGS for both object file
and build target. It's now possible to remove CFLAGS options like:
CFLAGS_REMOVE_krava.o += -Wstrict-prototypes
Committer notes:
This comes from the kernel's kbuild infrastructure, the subset that is
supported in tools/ is being documented at tools/build/Documentation/Build.txt.
