Update to the latest commit

• Point MASTER_SITES to FreeBSD's servers as we seem to have to host the distfile on our own (I wasn't able to find a way to get a tarball from upstream servers). Also, add a "regenerate-distfile" target to ease the process of updating the distfile in the future.
• Update MAKE_ARGS: setting CC there is no longer needed.
• Remove config.mk patches: it is sufficient for the sake of the port to just remove the include statement from the Makefile.
