[Xastir] FreeBSD port for Xastir 2.1.4 submitted.

[Tom Russo]

Turns out Magick-config was deprecated in ImageMagick6, and they want us to
use MagickCore-config instead.

I confirmed that the flags returned by FreeBSD's Magick-config for IM6 
are identical to those returned by MagickCore-config.

Magick-config was removed in IM7.

This is probably a simple matter to fix in Xastir's configure script, just
a matter of searching for MagickCore-config and using it if it's found,
and only searching for and using Magick-config if the new one isn't (indicating
a really old IM install).

We won't do a quickie release to address *this* issue.  But it should be 
fairly simple to get going, and then it's a matter of figuring out if doing it
actually lets us work with IM7, too.

I've opened an issue on github for it:
