The playstation2 port is back

In 2009 the playstation2 port was removed from the NetBSD sources, since it had not been compilable for months and no modern enough compiler was available.

Due to a strange series of events the code changes needed to support the (slightly unusual) MIPS CPU used in the playstation2 had never been merged into gcc nor binutils mainline. Only recently this has been fixed. Unfortunately the changes have not been pulled up to the gcc 4.8.3 branch (which is available in NetBSD-current), so an external toolchain from pkgsrc is needed for the playstation2.

To install this toolchain, use a pkgsrc-current checkout and cd to cross/gcc-mips-current, then do "make install" - that is all.

Work is in progress to bring the old code up to -current. Hopefully a bootable NetBSD-current kernel will be available soon.
