powerpc: rework sparse for lib/xor_vmx.c
Sparse doesn't seem to be passing -maltivec around properly, leading
to lots of errors:
.../include/altivec.h:34:2: error: Use the "-maltivec" flag to enable PowerPC AltiVec support
arch/powerpc/lib/xor_vmx.c:27:16: error: Expected ; at end of declaration
arch/powerpc/lib/xor_vmx.c:27:16: error: got signed
arch/powerpc/lib/xor_vmx.c:60:9: error: No right hand side of '*'-expression
arch/powerpc/lib/xor_vmx.c:60:9: error: Expected ; at end of statement
arch/powerpc/lib/xor_vmx.c:60:9: error: got v1_in
...
arch/powerpc/lib/xor_vmx.c:87:9: error: too many errors
Only include the altivec.h header for non-__CHECKER__ builds.
For builds with __CHECKER__, make up some stubs instead, as
suggested by Balbir. (The vector size of 16 is arbitrary.)
