Subject: [PATCH 2/4] xtensa: do not build variants directory

None of arch/xtensa/variants/*/ has Makefile, so 'buildvar' is always
empty.

Perhaps, downstream variant code might be dropped in, but given the
fact that none of upstream variants builds anything in their variant
directory, I doubt this is needed.
