- I built this PR locally for my native architecture, (x86_64-glibc)

#### Notes:

There are some issues with the license. I've marked this as MIT, but the only available file (COPYRIGHT) doesn't state this explicitly. It appears to be a modified MIT license but Fedora wiki suggests it's compatible with MIT, GPL v2 and v3. 

Based on what we discussed on the IRC, this appears to be "nonfree", so are there any changes I'll have to make for this?
