This is needed to run Python on the Hurd, especially during the build of python-boot0. Adapted from https://salsa.debian.org/glibc-team/glibc/-/blob/glibc-2.31/debian/patches/hurd-i386/unsubmitted-clock_t_centiseconds.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.
