*: fix detection and usage of sys/cdefs.h

This header is non-standard (though present on many systems) and
there is no standard for what it should or should not define.

Remove it where it is not really needed. But add also a configure
check, so it can be used if available but otherwise fallback to
defining the needed macroes.
