s390: Add -m64 to KBUILD_CPPFLAGS
Some non-code files, like linkescripts, are preprocessed with the C
preprocessor and make use of regular kernel headers.
As -m64 is not passed to those preprocessor invocations this leads
to an inconsistency between __BITS_PER_LONG and the C type 'long'.
An upcoming consistency check will be tripped by this.
Make sure -m64 is also defined for those preprocessing steps.
As KBUILD_CPPFLAGS is inherited by both KBUILD_AFLAGS and KBUILD_CFLAGS,
drop -m64 from these variables.
