These three flags apply only to the kbuild makefile in which they
are assigned. They are used for all the normal cc, as and ld
invocations happening during a recursive build.
- Note: Flags with the same behaviour were previously named:
- EXTRA_CFLAGS, EXTRA_AFLAGS and EXTRA_LDFLAGS.
- They are still supported but their usage is deprecated.
ccflags-y specifies options for compiling with $(CC).
