i386: Don't use ASM_OUTPUT_DEF for TARGET_MACHO

ASM_OUTPUT_DEF isn't defined for TARGET_MACHO.  Use ASM_OUTPUT_LABEL to
generate the __x86_return_thunk label, instead of the set directive.
Update testcase to remove the __x86_return_thunk label check.  Since
-fno-pic is ignored on Darwin, update testcases to scan or "push" only
on Linux.
