Hard disk cleanup

Did some cleanup on my hard disk. Went from 300MB free, to this:

wouter@rock:~$ df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/hda5              55G   39G   17G  70% /

I don't need three unpacked toolchain sources (for three cross compilers), outdated Debian CD images, or 5GB worth of backups of my server from a year ago, so I wiped them off my disk. Ought to do that more often, I think.
