* init.cfg (require_gcc_shared_): A new function to check that we can build shared libraries in the particular manner we use in our tests. * tests/cp/nfs-removal-race.sh: Use require_gcc_shared_. Then fail rather than skip, if the actual shared lib build fails. * tests/df/no-mtab-status.sh: Likewise. * tests/df/skip-duplicates.sh: Likewise. * tests/ls/getxattr-speedup.sh: Likewise. Reported in http://bugs.gnu.org/14024
