Warner Losh c96eb6d2e8 Add -q. this will cause the warning messages about missing
directories to not be printed.  This is from OpenBSD (and I think
NetBSD also) and makes our mtree more compatible with other BSDs.
This makes cross compilation easier than it was before.  Other changes
will be needed to allow NetBSD or OpenBSD to cross build on FreeBSD,
but this is a start.
