s4-waf: support the use of system libraries
distros can set --bundled-libraries=NONE to force use of all system libraries. If the right version isn't found then configure will fail. Users may choose which libraries to use from the system, and which to use bundled libs. The default is to try system libs, and use them if their version matches the one in the source tree.
