Log Message:
Expand ONLY_FOR_PLATFORM: the package internally thinks it supports
Solaris, so enable that; and if it works on NetBSD and Dragonfly with
a single "bsd" setting we can reasonably assume that it will work on
FreeBSD and OpenBSD (and MirBSD and Bitrig) with only minor
adjustments.

These probably won't all quite work out of the box yet, but that's
what bulk runs are for.
