Update to what I'm currently using. Lots of changes...

1) Allow selection of binutils/gcc/gdb/kernel headers to build, although
   some of the older tool patches probably need updating.
2) Rework gdb build so that remote debugging now works with gdbserver.
3) Misc. other package updates.3) Misc. other package updates.3) Misc. other package updates.

+Warning!  The powerpc patch (rs6000/linux.h) is hack-ish and would
+definitely need to be improved to be acceptable upstream.  Also,
+this patch isn't complete as it only supports i386, arm, mips, and
+powerpc (rs6000).
