The cracklib,2.7.tgz has moved to a different site and renamed to
have a .tar.gz suffix instead. The two files were compressed
differently, resulting in a different MD5 checksum.
Also, portlint seems to want a COMMENT line in the Makefile, obviating
the need for the pkg-comment file. I've added the former and removed
Fix: Use patch -E to actually delete the pkg-comment file.
