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.
