If the intention is to check i386/x86_64 excluding UML, testing
CONFIG_X86_{32,64} is simpler.

The reason for checking __i386__ / __x86_64__ was perhaps because
lib/raid6/algos.c is built not only for the kernel but also for
testing the library code from userspace.

However, lib/raid6/test/Makefile passes -DCONFIG_X86_{32,64} for
this case. So, I do not see a reason to not use CONFIG option here.
