+Subject: configure.ac: fix FTBFS with new glibc
+
+glibc moved clock_* functions from librt to the core libc. As a result,
+clock_gettime is no more a suitable symbol to use when finding librt.
+Look for mq_open instead.
+Reference:
+http://www.sourceware.org/git/gitweb.cgi?p=glibc.git&h=6e6249d0b461b952d0f544792372663feb6d792a
+
+Fixes a FTBFS in Fedora Rawhide.
