Various mips.
Seems like the fix for this fix still doesn't fix everything?
Yes, there are more binutils problems. The current kernel code does not correctly
detect binutils versions such as 2.24.90, where the third level version number
is >= 10. See the discussion in [1], and the fix from James Hogan in [2].
If I find the time, I'll extend my test scripts to run some mips builds
with different binutils versions.
