I'd find it confusing having an abi that wasn't supported on the thing I
was building for, but whatever.

ish.  n32 is a 64bit variant, not supported on 32bit cores. The default
should be based on the ISA selected, as in my

+	default BR_mips_ABI_O32 if BR_mips_32 || BR_mips_32r2
+	default BR_mips_ABI_N32 if BR_mips_64 || BR_mips_64r2

With whatever naming convention you want to apply of course.

And o32 should end up as just 32 by the time it gets passed to gcc configure.
