Documentation/prctl: don't build tsc tests when cross compiling
The following was seen in linux-next build coverage, which is somewhat
unique since it uses powerpc host to cross compile x86:
Documentation/prctl/disable-tsc-on-off-stress-test.c:36:1: error:
impossible register constraint in 'asm'
Documentation/prctl/disable-tsc-ctxt-sw-stress-test.c:34:1: error:
impossible register constraint in 'asm'
Documentation/prctl/disable-tsc-test.c:36:1: error: impossible
register constraint in 'asm'
It probably makes sense to just skip building these tests when
we are cross compiling.
