Subject: [PATCH] Make the build scripts work on FreeBSD

Make the source build less shell-fragile by deriving version macros in make,
failing header generation when the result is blank, and using portable bash
shebangs for the touched scripts.

This preserves the current build flow while making it work on FreeBSD hosts
that do not ship bash at /bin/bash and that expose the make recipe ordering bug.
