Really? Softfloat is a lot faster than kernel emulation.

You should use linux-uclibc for OABI.

Hmm, could you try with gcc 4.3.4? I've compiled OABI with 4.3.4 without
problems, but I've never tried 4.4.x.

Remember to run make clean after any toolchain changes.

Don't do that! Buildroot is designed to work without root permissions,
and I give absolutely NO guarantee that we won't make a mistake and
accidently overwrite/delete something, especially if you use a git
snapshot.
