Require rlibs for dependent crates when linking static executables

This handles the case for `CrateTypeExecutable` and `+crt_static`. I
reworked the match block to avoid duplicating the `attempt_static` and
error checking code again (this case would have been a copy of the
`CrateTypeCdylib`/`CrateTypeStaticlib` case).

On `linux-musl` targets where `std` was built with `crt_static = false`
in `config.toml`, this change brings the test suite from entirely
failing to mostly passing.

This change should not affect behavior for other crate types, or for
targets which do not respect `+crt_static`.
