Re: [PATCH 1/3] Makefile: use $(ALL_CFLAGS) in $(HCO) target

> On platforms that can run `make hdr-check` but require custom flags,
> this target was failing because none of them were being passed to the
> compiler. For example, on MacOS, the NO_OPENSSL flag was being set but
> it was not being passed into compiler so the check was failing.
