Add EABI C examples#176

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. |

I drafted this to prompt me to add the extra tests, but actually these tests are better than no tests so I'm undrafting this so we can merge it. I'll make an issue to add more tests later. |

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.My fix for cc-rs was merged and released.
See #185 for additional tests we might want to add later.
