linux host, mips-tx39-elf target, for example.
All non-SGI MIPS targets would be affected.
>Description:
Building libstdc++-v3 for a non-SGI MIPS target such as
mips-tx39-elf results in a build failure such as:

/home/jlarmour/sourceware/gcc/build/mipstx39-elf/mips-tx39-elf/libstdc++-v3/include/mips-tx39-elf/bits/atomicity.h:33:21: sgidefs.h: No such file or directory

This is because config/cpu/mips/bits/atomicity.h includes
<sgidefs.h> unconditionally. This file AFAIK only exists
on SGI systems. Not on newlib targets, nor probably 
Linux/MIPS. 
>How-To-Repeat:
configure --target mips-tx39-elf
make
>Fix:

Probably the easiest fix is simply to reflect the current
reality:

Index: configure.target

So the generic case will pick up the rest.
