* ABI A property containing the library ABI loaded (or -1 if unavailable)
*
* @param aName
* The name of the library to load, without the "lib" prefix or any
* file extension.
*
* @param aABIs
* An array of library ABI's to search for. The first one found will
* be loaded and the loaded ABI will be saved on the exported object.
*
* @param aDefines
* A function which will be called to load library symbols and create
* types. The function will be called with one parameter, which contains
* several functions for binding symbols. The "this" object will be
* the exported object, on to which you can should types and symbols.
*
* @param aGlobal
* The global object on to which we export an object. This must be a
