Unbreaking ports with n64 MIPS.

[Warner Losh]

Hi Juli,

I'd be fine with mips64 and mips64eb being the same, and moving from the former to the latter as the uname reported value. I almost did it when I was doing the stuff, but the pedants were against me and I didn't have any good amo to push back at them.  This would be a good reason.  The code was a little simpler when I always specified the eb on the end for all mips ports, so there's some tricks in the tree to keep expressions from getting too gross you'll have to watch out for.

As for IRIX, n32 binaries were run on it, but there never was a n32 kernel that I recall.  It was just a funky ABI that you could compile your programs to if they had problems with the n64 ABI.  So the OS didn't report anything special there.  Our notion of an n32 kernel is historically a bit funkadelic.
