I've fairly radically changed the MinGW instructions in the README here as well. I've attempted to start from a completely fresh MSYS2 install and follow these instructions to get a compiler bootstrapped, and they appear to be working. The biggest change is that we no longer request a custom download of the old 4.9.2 compilers, as it appears that whatever bug was there before is now gone. |

The LLVM build system is somewhat picky about which Python is used to build it as it's known to be incompatible with the default `python2` package that ships with MinGW. This was previously detected for MSVC builds but the logic was left out for MinGW by accident (now that we've switched to cmake builds for LLVM everywhere). This corrects the `./configure` check and also updates the `README.md` accordingly. Additionally, a number of instructions were updated to work with the most recent copy of MSYS2. Closes rust-lang#34489
