RFR: JDK-8147795 Build system support for BSD

[Greg Lewis]

I've replied to Magnus separately on the freebsd-java mailing list.  This
is great and I'd love to see it in either the jdk9 mainline or the bsd-port
repo of jdk9.

The big barrier has always been the volunteer effort required to get past
the TCK and fix whatever relatively non-mainstream bugs that are lurking
for BSD.  I'm aware of people running openjdk8, for instance, for
production purposes on FreeBSD and the OpenBSD and NetBSD likewise seem
to be kept relatively up to date (or were last time I looked).

I haven't had time to work on the full jdk9 port but have been keeping the
repo up to date for when time became available or others were able to
contribute.  It is nice to see the latter starting to happen.
