I believe this sums up the current situation of Rust on mips*. Hopefully
all the issues are covered.

This is probably the 128-bit integer bug (wrong results from 128-bit
integer arithmetic). It was fixed in LLVM 5.

I don't recall seeing any ld errors in my testing (although I have been
using upstream nightly rather than the Debian packaging). It would be
good to know what the error was :) I'll try building it again after my
mips64 ABI PR gets merged.
