Consider adding readme and licensing info

[jprjr]

Hi there, this repo popped up in my GitHub feed. From a stand-alone, only-looking-at-this-repo perspective, I'm able to determine it's a C compiler (though that piece of info is github-specific), but not much else.

Just thought I'd mention this, having a brief README file describing what this repository is would likely help with discovery, preservation, etc. Same applies to a LICENSE or COPYING file.

Licenses are in their respective folders, a README might be of use.

It may also serve as a compiler for homebrew GBA games, it isn't just something that's used for those

Bumping this, should be prioritized.
