Sounds sensible. I would prefer to not touch the release target right
now, as I don't have xz installed, noone else needs it and I already
have my own release script signing the tarballs and uploading them.

Makes sense. Why would we want to run the -clean targets of all the
individual packages first? That just tends to take ages (and fails on
buggy packages), and we're nuking the TARGET_DIR afterwards anyway.

Same comment about TARGETS_DIRCLEAN.

dirclean already gets rid of those dirs.

The git archive part is fine by me, but my script just expects the
.tar.gz, so I would like to keep it like that (for now atleast).
