Hi folks

The attached patch changes the powerpc main Makefile from using the override
make directive to KBUILD_CFLAGS and similar.

The override approach breaks with both variants "CC=3Dgcc-4.3 make" and
"make CC=3Dgcc-4.3". The first ignores the given value completely because
the toplevel Makefile includes a CC definition:

| $ CC=3D"gcc-4.3" make V=3D1
[...]
|  gcc -m64 -Wp,-MD,init/.main.o.d

The second does not add -m64:
| $ make CC=3D"gcc-4.3" V=3D1
[...]
|  gcc-4.3 -Wp,-MD,arch/powerpc/kernel/.asm-offsets.s.d

The patch changes the CC, AS and LD overrides into changes of
KBUILD_CFLAGS, KBUILD_AFLAGS and LDFLAGS similar to arch/s390/Makefile.
