status of ports and clang

I have recently been able to get the new build cluster on pointyhat-west
set up to run full builds of ports with clang on amd64-9.  I have documented
the latest results on the wiki:

  http://wiki.freebsd.org/PortsAndClang

If you are interested in working on ports being built via clang, this
is your place to start.

Please also note that now that we have up-to-date builds going, it is
not as useful to us to report individual clang build failures.  Patches
to fix problems are, of course, highly welcome.
