the logic was such that if the bundle name already had the specified
extension which was not the default extension, the default extension
would be appended, too. i don't think that was the intention ...
now we simply put the default into QMAKE_BUNDLE_EXTENSION if its empty -
the variable is not used anywhere else where it would be expected to
preserve its emptiness, so this is safe.
