Linking JS files from libraries

[chpio]

hi,

it seems that it's not possible to link javascript files from a rust library at the moment. The usual practice is by setting the --js-library $path_to_js_file emcc-linker argument. But setting linker arguments from a lib is not allowed in rust (#36176, rust-lang/cargo#1293).

I can think of two possible solutions for this:

1. allowing link args when compiling to asm.js/wasm
2. using the extern-linking syntax and converting the link to an --js-library emcc argument to pull in the js file:

#[link(name="my_js_file")]
extern {
    fn add(a: size_t, b: size_t) -> size_t;
}

Can we get a A-asmjs tag here?

I'm closing this in favor of stdweb's inline js and wasm imports.
