Support for GNU/kFreeBSD.
GNU/kFreeBSD is an experimental OS provided by the Debian project, consisting
of a FreeBSD kernel and GNU userland/libc. For a small number of cases, this
offers advantages over a more common GNU/Linux combination, such as fast
in-kernel support for ZFS storage.
This patch changes various ifdefs, either using __FreeBSD_kernel__ where a
trait from the kernel is what matters, or __GLIBC__ where a trait from the
C library matters.
This patch set has been carried downstream, in one form or another, since
1.2.3.1-1.
