Fix MinGW target detection in raw-dylib LLVM target doesn't have to be the same as Rust target so relying on it is wrong. It was one of concerns in https://github.com/rust-lang/rust/pull/88801 that was not fixed in https://github.com/rust-lang/rust/pull/90782.
The codegen crate contains the code to convert from MIR into LLVM IR,
and then from LLVM IR into machine code. In general it contains code
that runs towards the end of the compilation process.
For more information about how codegen works, see the rustc dev guide.
