Set crt_static_allow_dylibs to true for Emscripten target And add a test. This is followup work to rust-lang/rust#151704. It introduced a regression where cargo is now unwilling to build cdylibs for Emscripten because `crt_static_default` is `true` but `crt_static_allows_dylibs` is `false`. Unfortunately the added test does not fail without the change because the validation logic is in Cargo, not in rustc. But it's good to have some coverage of this anyways.
rustc_target contains some very low-level details that are
specific to different compilation targets and so forth.
For more information about how rustc works, see the rustc dev guide.
