Expose C versions of `libm` functions in the `cb` crate `compiler_builtins` exposes an `extern "C"` version of `libm` routines, so add the same here. There really isn't much to test here (unless we later add tests against C `libm` suites), but one nice benefit is this gives us a library with unmangled names that is easy to `objdump`. In accordance with that, also update `cb` to be a `staticlib`. Unfortunately this also means we have to remove it from the workspace, since Cargo doesn't allow setting `panic = "abort"` for a single crate. 2025-01-12 07:43:24 +00:00			`#[path = "../../configure.rs"]`
