#15329: Please don't use -lgcrypt when building with GnuTLS

--------------------+--------------------------
 Pidgin doesn't use libgcrypt directly and yet it links to it through
 -lgcrypt when building with GnuTLS. Latest GnuTLS 2 releases can use
 nettle instead of libgcrypt, and GnuTLS 3 doesn't have libgcrypt support
 at all. Even when built with libgcrypt, GnuTLS doesn't require
 applications linking to it to explicitly link to libgcrypt (it would be
 the case only if it was using libgcrypt in its headers). So -lgcrypt can
 be safely removed from configure.ac.

 I hope I'm not doing bad setting a milestone for this ticket. I didn't
 find any suggestions not to do so in TipsForBugReports.
