[Aboriginal] Package upgrades and cleanup work.

[Rob Landley]

1) Linux 3.0 is out: it broke busybox.

Fixes (to busybox):

A) rip out the redundant sysinfo definition busybox block copied out of
stale header files.
B) Zap two applets Denys inexplicably added which reproduce netcat
server mode.

I also needed to update the noperl patches, not because the perl removal
changed but because the context did.

2) Updating to uClibc 0.9.32: sh4 and sparc broke.

Fixing it:

Still using pthreads.old rather than nptl, I'll worry about that later.

3) Changed the boot scripts to mount devtmpfs on /dev instead of
mounting a tmpfs there and running mdev -s.  (This is simpler, and gives
us free hotplug support.  The permissions only allow root to access most
stuff, but mdev is like that with no config file.)

4) Ripped out the control-images from the aboriginal repo (now that
they're in their own repo).  Might have missed something or left some
unconnected bits, but I think I got it all...

Vaguely on track for a release at the end of the month, I think...
