fetch: skip target tests when cross_compile is disabled

It was reported in #5864 that the fetch-by-target tests fail when run on a non-x86 platform.  This is due to the cross_compile module being disabled when running on non-x86 platforms.  Fix this by skipping the two fetch tests which rely on the cross_compile module, when cross_compile has been disabled.
