mips-sgi-irix6.5 installation

[Cyril Fischer]

Hi, I am not able to successfully compile egcs-1.1.2 on sgi indy (R4000
cpu).  The compilation stops when assembling the libstdc++.so for
-mabi=64. (due to the non-existent  64 bit library libm.so) As we have
32-bit cpu, we do not use 64 bit mode. How can I prevent the -mabi=64
step of the build procedure? I would like to avoid the manual editing of
makefiles.

Thanks,
Cyril
