It's necessary to do this in order to fix ckb's compilation, now that
fixupPhase rejects derivation results containing references to the temporary
build directory. It seems like good practice so I've added it to the
other packages that I maintain.
The current URL is broken, upstream has moved the download from .../files/ to
.../files_legacy/. But after fixing that, starting hashcat results in:
$ ./result/bin/hashcat
ERROR: this copy of hashcat is outdated. Get a more recent version.
So just update to latest.
New releases are on github, the license is now MIT and there are build
system changes.
