Hi,

When I try to build glibc-2.3.3 on mips linux - it breaks as shown below:

Some experimentation with "gcc -E" revealed that in the compiler I am using
(by default),

_MIPS_SIM is set to 1
_ABI032 is set to 1
_ABIN32 is not defined
_ABI64 is not defined

I tried compiling a "hello world" program with "gcc -mabi=32" and it works.

If I try "gcc -mabi=n32" it breaks at the linking stage as below:

sara@eyeore: [over] ~/tmp$ gcc -mabi=n32 -o v v.c
/home/sara/usr/local/lib/gcc/mipsel-unknown-linux-gnu/3.4.2/../../../../mipsel-unknown-linux-gnu/bin/ld: /tmp/ccnz0jlk.o: ABI is incompatible with that of the selected emulation /home/sara/usr/local/lib/gcc/mipsel-unknown-linux-gnu/3.4.2/../../../../mipsel-unknown-linux-gnu/bin/ld: failed to merge target specific data of file /tmp/ccnz0jlk.o /home/sara/usr/local/lib/gcc/mipsel-unknown-linux-gnu/3.4.2/../../../../mipsel-unknown-linux-gnu/bin/ld: BFD 2.15 assertion fail elfxx-mips.c:1899
collect2: ld returned 1 exit status
sara@eyeore: [over] ~/tmp$

What should I do to fix the build?
