- 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")
