[distcc] FreeBSD patch to distcc-0.4

[Claes Wallin]

Apparently, mknod doesn't work exactly the same on FreeBSD and Linux.
Without this fix, distcc-0.4 won't work on my FreeBSD 4.5 box (it has
to be root to use mknod, and even then it doesn't seem to do its stuff).
Now it works just fine in both FreeBSD and Linux.
