Hi again,

I added preliminary stub glue to dietlibc that let it compile for mips64, but
as I did not yet touch any assembly the resulting binaries will most likely not
work correctly (e.g. crash on startup).
At least this let's all dietlibc depending packages build for now (yay!), so
that we can concentrate on really implementing mips64 support in dietlibc
instead of marking any package depending on dietlibc to not support mips64, ...
OK, I Backed out all my -mips64 dance-a-rounds for the dietlibc dependencies. Now, with
the current svn tip I can build right up to the stage 1 GCC, but it fails in that build
with a compiler segfault. I remember that I was also getting an internal compiler error at
this stage back in May with with GCC 4.5.0. So I guess that GCC 4.5.X is still not very
healthy on Mips64. I tried upgrading some of the dependencies to GCC, to see if I could
get the segfault to go away, but that did not help Mips64 at all, but these may come in
handy for the other architectures, if you want to bump up the versions of gmp,mpfr,ppl and
mpc. Here are some patches that will do that, but they did not fix my trouble, so I think
I will have to pin the GCC version to 4.4.3 until this is sorted out.

PS: I do not have a mips64 silicon near me at the moment, I think I already
wrote somewhere that I stored my Sgi Octane (2 IIRC) at my parent attic as it
was too loud for the office, ... Maybe someone wants to send in (as in donate)
less noisy MIPS64 hardware?
