If anyone has any insight I'd love to hear it.
Meanwhile, I'll continue to investigate...
Currently I'm working on bootstrapping llvm-gcc4 on mingw32 platform.
There are some serious miscompartibilities preventing build. I'll let
know the results.
Anyway, it's common knowledge, that msys itself have some bugs which
might lead to several problems while building gcc. Mingw32 itself is
build inside stripped cygwin shell 
Is it possible to build using MINGW, but without using msys?
All along I've been assuming that I needed msys.

Unfortunately, no (especially, if you want to build gcc). LLVM and gcc
uses auto* machinery, which depends on sh, sed, sort, etc. So, you should
use (at least for configure) some amount of "shell-tools".
As for LLVM itself, it's possible (in theory, I haven't tried it )
to generate config.h by hands and than just use make.
