[PATCH v2 3/5] kbuild: call cc-option with the current set of KBUILD_CFLAGS

[Nicholas Piggin <npiggin@gmail.com>]

In some cases, the options that gcc will accept depend on options it
has already been given. For example -m32 / -m64 and -mbig-endian /
-mlittle-endian can have this affect.

Passing in KBUILD_CFLAGS to cc-option allows an architecture to
set such basic machine types at the beginning, rather than override
CC itself.
