Add --enable-gnutls option

Previously HAVE_LIBGNUTLS was never set in config.h even if gnutls was detected as AC_CHECK_LIB default action-if-found was overriden by enable_gnutls=yes This patch adds an --enable-gnutls option and will call AC_CHECK_LIB with the default action to write HAVE_LIBGNUTLS in config.h Signed-off-by: Fabrice Fontaine <fabrice.fontaine@orange.com>
