qemu-sparc can decently run debian-40r8: gcc and all the other stuff
seem to work.

Most versions of the NetBSD boot. Some require the original OBP
though. The only known to me version which definetely doesn't boot is
3.0.2.

Also since the last dma fix Solaris 2.4-2.5.1 seems to be also fully
functional. Don't have a suitable compiler to check whether it's
working under Solaris though.

Debian-40r8 should have all the necessary stuff to build the uClibc
toolchain, right?
