If it's a run-time property, it should really be a run-time check, otherwise cross-compilers will break. There are things that are not open to run-time checks, though, like the presence of symbol versioning support in the dynamic loader. Ideally, musl applications would be built with a toolchain that completely lacks symbol versioning support, but that's not what happens in practice.
