Subject: [2.7] closes bpo-14353: Fix detection of bind_textdomain_codeset in
 libintl. (GH-13265)

In Python-2.7, we were only searching for bind_textdomain_codeset in
libc.  We should have also checked for it in libintl.  This change from
Mel Flynn https://bugs.python.org/file24918/python27-configure.in.patch
fixes that.
