It's worth comparing this to the docker image we provide... that logic is;

# msys2 with additional required packages
DownloadAndCheck $env:TEMP\msys2.tar.xz https://github.com/msys2/msys2-installer/releases/download/2021-02-28/msys2-base-x86_64-20210228.tar.xz 3f2ceb097a081789d9d497e0d3df8d99c16a1591b9984b0469440cd5bfa65092

I see this msys2.tz image does expand into msys64/ paths, not msys2, and agree with your change. A question is, have we missed other oddities like link.exe (why did msys2 project not name this ld?) that we compensate for in our toolchain assembly? In any case, LGTM.
