Trevor Gross 0a5785734c c-b: Ensure check-cfg is set for all targets
Emscripten and OpenBSD exit out of the build script early. Since
02014b06c1a3 ("c-b: Turn `mem-unaligned` from a feature to a cfg"), this
meant that the exit happened before all `rustc-check-cfg`s had been
emitted.

Rework the logic so these only skip the C build rather than the rest of
configuration.

compiler-builtins and libm

This repository contains two main crates:

  • compiler-builtins: symbols that the compiler expects to be available at link time
  • libm: a Rust implementation of C math libraries, used to provide implementations in core.

More details are at compiler-builtins/README.md and libm/README.md.
