For glibc 2.9 (F10) it would suffice to just have .27, but for rawhide
.29 introduces futex bitset and realtime clock support, which means an extra
syscall for every threaded program.  We could bump it in steps, first start
requiring .27 and then if .29 is sufficiently stable in a month (or when
we really need to freeze), rebuild just glibc requiring a newer kernel.
