+Taken from: https://salsa.debian.org/glibc-team/glibc/-/blob/9ce19663f00176f30d6eab29fd14db3e7cd53dcf/debian/patches/hurd-i386/local-clock_gettime_MONOTONIC.diff
+
+Use the realtime clock for the monotonic clock. This is of course not a proper
+implementation (which is being done in Mach), but will permit to fix at least
+the iceweasel stack.
+
+vlc however doesn't build when _POSIX_CLOCK_SELECTION is enabled but
+_POSIX_TIMERS is not, and they refuse to fix that (see #765578), so disable the
+former.
