This looks great to me, thanks @FenrirWolf! I don't mind landing this as-is and and the location of this makes sense to me.

Mind adding a comment as to the intention here? (a semi-nicer compiler error message)

Basically I've only verified bindings for ARM so it needs to fail in some fashion for things that aren't ARM. the uclibc module does something similar so I just imitated that: https://github.com/rust-lang/libc/blob/master/src/unix/uclibc/mod.rs#L1771-L1782

Oh yeah this is fine, it'd just be good to have a comment here

Sure, I can definitely add a comment. Should I also change the unsupported target module to target_arch_not_implemented or something similar?

I think this may be unused?

Right, I forgot to remove that earlier. I'll do that when I push another fix that I need to make.

Or not. Turns out I actually use that import after all. FD_CLR() and friends depend on it and I'd just forgotten to include them last time around.

Add experimental newlib bindings I'm not sure how much desire there is for something like this in the libc crate, but I've been working with a newlib-based toolchain for a while and thought I'd throw this PR up and see what happens. These bindings are more specifically targeted towards the devkitARM toolchain from http://devkitpro.org rather than newlib in general. I'd be happy to try making things more platform and toolchain-agnostic, but I'm not completely sure what the best way to do that is. I can move more of the arch-specific bindings to the `arm` folder, but should there also be a `devkitarm` subdirectory to further separate specific bindings from other newlib implementations? There's also the question of if the bindings should live in the `unix` directory in the first place. Newlib aims to provide a unix/posix-like environment and it would be nice to inherit common unix definitions by default, but it can target anything from embedded devices to custom userlands, and as such it often lacks APIs that are common in other libc variants, such as pthreads.

☀️ Test successful - status-appveyor, status-travis |
Bump to 0.2.25 To get newlib bindings (#646) and other stuff on crates.io
