Use Gnulib's `localcharset', with local patches.
This follows Bruno Haible's suggestion at
<http://lists.gnu.org/archive/html/guile-devel/2011-11/msg00055.html>.
* m4/gnulib-cache.m4: Add `gl_LOCAL_DIR'; use `localcharset'.
* Makefile.am (EXTRA_DIST): Add gnulib-local/lib/localcharset.[ch].diff.
(TESTS_ENVIRONMENT): New variable.
* gnulib-local/lib/localcharset.c.diff,
gnulib-local/lib/localcharset.h.diff: New files.
* test-suite/Makefile.am (TESTS_ENVIRONMENT): Add
@LOCALCHARSET_TESTS_ENVIRONMENT@.
* test-suite/standalone/Makefile.am (TESTS_ENVIRONMENT): Likewise.
