It should work fine as system ebuild, using it in crossdev requires the
toolchain to be patched to understand musl isn't a bare-metal libc (the
default search path change between those)

could you explain to non-gentoo users (me included) what this is and 
what to do with it ?

It's essentially a musl build script for use with emerge (the portage
system). I don't think you'll find it useful if you don't use Gentoo.
I do however, so thanks Luca!

Thanks,
Kyle.

It is the recipe to build musl in gentoo (sabayon, and other derivatives).

It should be useful for people wanting to try musl on gentoo and
obviously I'd like to have more feedbacks and help in getting musl
working on crossdev w/out hacks.
