(guix build syscalls) provides %prctl which assumes that the “prctl” is
available.  On Debian GNU/Hurd (which the custom glibc
2.23-hurd+libpthread-20161218) this is not the case.

Since this is used for “set-thread-name”, which is used by (guix scripts
substitute), Hurd systems cannot query for substitutes.
