Add the ability to pass a list of alternative bdf fonts to this port.

This  can be  used  to generalize  building  of, say,  language-specific
versions of gd like ukrainian/gd -- the controlling port will simply set
GD_FONTS to something like

GD_FONTS="/usr/ports/distfiles/x-koi8u.tgz koi6x10.bdf koi8x13.bdf \
	koi9x15.bdf koi12x24.bdf koi10x20.bdf"

And the new configure script will extract the bdf files from the tarball
and use the bdftogd perl script (bundled with the software) to regenerate
the sources.

No REVISION bump, because the default package is still the same...
