extend musl weak symbols mapping

[reubenmiller]

Extending the musl weak symbol mappings to resolve #179.

The symbol list was generated via scrapping the header files from the musl source code at (http://git.musl-libc.org/cgit/musl/)

fyi: I'm fairly new at the compiler stuff, so if this PR went to far than I'm happy to adjust as directed.

Thanks!

I don't think we need to add constants because usually they're just a #define in C, you can't refer to it in Rust so it's not needed here.

Thanks for the assist. I leaned towards adding add #defines since it was generally easier to remove than add.

It'd be great if you can confirm that this actually fixes #179 for your project, thanks!
