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.
