Emacs already has a solution for all this, in the MS-Windows build
(which already loads these libraries dynamically). So what's needed
is to use the same arrangement on other platforms, which currently
link statically against these libraries.
In nutshell, the version against which Emacs was compiled is recorded
at build time, and then tested against the library at load time.
