 No question about it, but it makes sense only if accompanied with the 
respective bug report against GCC.  Then some areas of the MIPS o32 ABI 
are obscure enough or plainly wrong (= useless as is -- see e.g. the 
R_MIPS_PC16 relocation), so that using a live piece of software instead is 
reasonably enough.  And o64 does not even exist. ;-)
