This does a very basic EABI check. We don't examine all the details, but it's enough to see whether we agree on short-enums, or the hard-float ABI. CI updated to install GCC (for cc-rs) and libclang1 (for bindgen). cc-rs doesn't currently support all our targets, so this will fail.
It requires a C compiler and most CI jobs don't have one.

Updated to use a fork of cc-rs at https://github.com/jonathanpallant/cc-rs/tree/add-more-bare-metal-arm, with a bunch of fixes for these targets. The upstream PR is at rust-lang/cc-rs#1753. |

This is to check Rust/C interop (but only as a basic smoke test).
It looks like cc-rs needs updating to understand all these targets, as you get errors about "this architecture doesn't have an FPU" where cc-rs failed to add an
-mfpu=blahoption automatically.
