It used to depend on a bunch of files from the FreeBSD source tree.
But the import of gdb-4.18 and the restructuring connected with
that broke the port. I have created a second distfile containing
the needed files, and this port now gets them from there.
Also mark this port broken for everything except i386/elf. I don't
have time to fix the other platforms before the 3.3-RELEASE ports
freeze.
