You can easily fire up a mips32 / mips64 emulator build - cross-build
a world+kernel, build an image, then run qemu-devel to boot it.

You should be able to get a 32 bit soft-float mips environment inside
there which you can use to trigger it.
(And also run whatever other floating point validation suite you may hvae.)
