This bug was created some time ago to bring order to the platform plugin 
problem. It proposes configure arguments for selecting the platform 
plugins to build as well as a way to select the default platform plugin 
to use.

If there's a way to detect the environment you're running under that 
would be even better than a compiled-in default.
