I am seeing a new CI failure with the latest nightly rust version 1.86.0-nightly (43ca9d18e 2025-02-08):

 + cargo check -p libm --no-default-features
error: process didn't exit successfully: `C:\Users\runneradmin\.rustup\toolchains\nightly-i686-pc-windows-gnu\bin\rustc.exe -vV` (exit code: 0xc000007b)

rust version 1.86.0-nightly (43ca9d18e 2025-02-08) works correctly.

This happened attempting to build the libm crate; however, it looks like this is just failing to run rustc.exe -vV so it doesn't seem crate-specific. I am still investigating, some work at rust-lang/libm#506.

Reproduces just running rustc -vV with an i686-pc-windows-gnu host toolchain.

Do install msys2 in CI explicitly

Reverts rust-lang#136588.
Only papers over rust-lang#136795, but the root cause needs to be investigated (likely a bug in how `i686-pc-windows-gnu` is built?).

Seems like for whatever reason the msys2 installation here is needed for the 32-bit `i686-pc-windows-gnu` target, otherwise `rustc` distributed for that target seems to link against the 64-bit `libwinpthread-1.dll` and such. This revert is mostly just to buy time to investigate without having to debug why the build logic for the 32-bit windows-gnu target is wrong.

This reverts commit e060723, reversing changes made to a9e7b30.

From my testing it looks to me like something is forcing /mingw64/bin:/usr/bin:/c/Users/runneradmin/bin to be at the front of PATH. Even if we prepend other paths then it looks like these two get moved up front.
