// Ensure that rust-lld is used as the default linker on `x86_64-unknown-linux-gnu`
// and that it can also be turned off with a CLI flag.
//
// This version of the test checks that LLD is used by default when LLD is enabled in the
// toolchain. There is a separate test that checks that LLD is used for dist artifacts
// unconditionally.
