Re: MIPS libstdc++-v3 x86-x-mips-elf doesn't build

Well, whatever. 

I would prefer to have the mips port work like all the other ports. 
Having some of the ports use this header file, and define _MIPS_ISA or 
__mips, or whatever is bogus. There's got to be something consistent that 
the configure scripts can use to figure out what the eventual target is.

Eric, I've cc'd you because I believe you are the mips maintainer. If you 
can think of a way to do this, or can suggest a sane alternative, please 
advise.

In the meantime, the configure.target bits that turn on mips atomicity.h 
are being reverted. Sorry, HJ.

(In addition, the generic bits in mips/bits/atomicity.h have been excised.)

        * configure.target: Remove mips from cpu table.
        * config/cpu/mips/bits/atomicity.h: Remove generic
        versions. Comment sgidefs include.
