If politics enter the game, this becomes too much complex for me, sorry.

Is MSYS so old? IIRC its existence was first made public on 2001. At the
time I was an active MinGW-ist. (I'm getting old... :-)

As mentioned above, MSYS is a Cygwin fork, tweaked for MinGW
friendliness. However, as you point out, MinGW developers prefer to
build from Cygwin. Maybe this comes from the previous MinGW developers
(pre-MSYS) who used Cygwin extensively, maybe there are technical
reasons for doing so.

I'm having success building the LLVM libraries with CMake 2.6.1 on
MSYS, where 2.6 failed, IIRC. Maybe this was fixed.
