Outdated MIPS toolchain

[polachok]

I think we waste too much time on workarounds for its problems. It was built when debian squeezy was all the rage (almost 5 years ago). Let's just drop it and use something more modern.

Linux-mips website has a list of toolchains we can use.
I created a branch using CodeScape MIPS SDK. It currently fails on linking stage, but I thought it would be a good idea to ask of your opinion before researching it further.

Yeah I'd be totally down for using a newer toolchain, I definitely agree the one we're using is quite old! It was basically just the first one that I ran across :)

This seems to be the easiest way?
