You probably mean OABI and not O32.

Look at target/Config.in.arch
I was under the impression that OABI was 32 for mipsel and o64 for mips,
no?

I'm not too familiar with the mips matrix.. I will take a look how
mips32r2 should be configured (mips vs. mips64 vs. mipsel vs. ??; i.e.
both the endianess and the bit-depth have to be settable, AFAICS).

Thanks for the heads up.
cheers,
