This is a functionally equivalent, minimally invasive backport of #90044, which fixes the problem that compiling any binary with the target aarch64-unknown-linux-musl fails unless lld is used for linking (#89626).
I have tested this backport by building aarch64-unknown-linux-gnu, installing the std libraries for the -musl and -gnu variants in rustc-beta-aarch64-unknown-linux-gnu/rustc/lib/rustlib and running helloworld successfully for both targets on arm64 hardware.
