That's also my experience on appveyor (but I'm not compiling GHC itself):

https://github.com/LambdaHack/LambdaHack/blob/master/appveyor.yml#L50

Both versions of msys2 are present and I need to set path to the 32 version
to compile for 32bit. In this way I'm able to generate both 64bit
and 32bit binaries in a single appveyor run.
