| Subject: [PATCH] configure.ac: fix build failure when crypt() does not require |
| libcrypt |
| |
| Since commit 522246d20e4cd92fadc2d760228cb7e78cbeb4c5, the build fails |
| if "none required" is returned by AC_SEARCH_LIBS for libcrypt. |
| |
| Resolves: https://github.com/linux-pam/linux-pam/pull/235 |
| Fixes: http://autobuild.buildroot.org/results/92b3dd7c984d2b843ac9aacacd69eec99f28743e |
| Fixes: v1.4.0~228 ("Use cached 'crypt' library result correctly") |
