The following was seen in linux-next build coverage, which is somewhat
unique since it uses powerpc host to cross compile x86:
Documentation/vDSO/vdso_standalone_test_x86.c:49:2: error: impossible
register constraint in 'asm'
make: *** [Documentation/vDSO/vdso_standalone_test_x86.o] Error 1
It probably makes sense to just skip building these tests when
we are cross compiling.
