rust/tests/run-make/raw-dylib-cross-compilation/rmake.rs

// When cross-compiling using `raw-dylib`, rustc would try to fetch some
// very specific `dlltool` to complete the cross-compilation (such as `i686-w64-mingw32-dlltool`)
// when Windows only calls it `dlltool`. This test performs some cross-compilation in a
// way that previously failed due to this bug, and checks that it succeeds.
// See https://github.com/rust-lang/rust/pull/108355

//@ ignore-i686-pc-windows-gnu
// Reason: dlltool on this distribution is unable to produce x64 binaries
//@ needs-dlltool
// Reason: this is the utility being checked by this test
