This is similar to NO_FNMATCH but it uses wildmatch instead of compat/fnmatch. This is an intermediate step to let wildmatch be used as fnmatch replacement for wider audience before it replaces fnmatch completely and compat/fnmatch is removed. fnmatch in test-wildmatch is not impacted by this and is the only place that NO_FNMATCH or NO_FNMATCH_CASEFOLD remain active when USE_WILDMATCH is set.
