[RFA] The MIPS/Linux port

Like any new port, this is dependent on a fair number of other sources. If
you actually want it to work, for instance, you'll need:
- A recent CVS kernel from oss.sgi.com, to have ptrace behave right in the
first place.
- A patch I posted there which is still being considered, if you want to
debug programs that use the FPU and not have them become completely
confused.
- A compiler/assembler that emit debug info we can cope with. GCC 2.95.2
and binutils 2.10.91.* are fairly good for this. Note that:
* the mdebug information emitted when you use GCC 3.0 crashes gdb; I
posted a patch for this a week ago and got no comments.
* the stabs-in-elf emitted by recent binutils is not compatible with
the way any GCC version emits stabs for mips; this needs to be
addressed in either binutils or gcc, and HJ posted a potential patch
for it two days ago.
* Dwarf2 debugging does not appear to work properly; I'll look into
it once the dust settles a little.
The only outstanding gdb patches on which this one really depends are the
two mips-tdep.c patches posted today. I also have a few more for ABI issues
which still need some tweaking.
I imagine I break multi-arch in all sorts of unpleasant ways, etc. etc. I'd
like to get this in and then fix it up, if possible; it's a little on the
large side :) I imagine it'll take a couple iterations anyway, though.
Comments welcome! (approval even more so)
