Myk Melez 7978cd2fe4 Bug 1482810 - set COMPILE_FLAGS var to hide warnings for Rust crates r=chmanchester
In conjunction with the cc crate changes in https://github.com/alexcrichton/cc-rs/pull/342 (which I'll land in https://phabricator.services.mozilla.com/D4699), this hides warnings generated by C code in Rust crates (by removing warnings flags from CFLAGS when compiling Rust libraries).
