Default to an executable "--crate-type bin", but if -shared is specified, use "--crate-type lib"
For executables, add a main shim, like https://github.com/bjorn3/rustc_codegen_cranelift/blob/7ff01a4d59779609992aad947264abcc64617917/src/main_shim.rs

-shared should give a cdylib. -c or something like that should give an rlib (crate type lib, actually a renamed .a file) There are also staticlib (.a without rust metadata) and dylib (.so with rust metadata in the .rustc section)

oops, right

There are also staticlib (.a without rust metadata) and dylib (.so with rust metadata in the .rustc section)

I think it's ok not to support these at first.

std::rt::lang_start_internal, not being a template function, apparently requires linking with libstd
