[PATCH 2/2] Add a test for glibc's Bugzilla bug #12378.

[James Youngman]

From: James Youngman <address@hidden>

* m4/fnmatch.m4: Use gnulib's fnmatch if the system fnmatch
doesn't allow the literal matching of a lone "[" (which is
required by POSIX).
* tests/test-fnmatch.c (main): Check that "[/b" matches itself.
