I did a quick hack:
20 files changed, 40 insertions(+), 3051 deletions(-)

All the leon stuff is kept and there is room for more cleaning up.
The kernel can build a sparc32_defconfig with the Gaisler toochain.
This was a one hour quick hack that I cannot commit - it needs to be
split up to allow some resemble of review.

And it touched only arch/sparc/ - no sparc32 specific drivers were
dropped.

If we decide to chase this and we can drop sun4m/sun4d then maintaining
leon will be simpler as a nice side effect.

	Sam
