   [...] BSDL doesn't allow relicensing under the GPL. It doesn't have
   LGPL like clause that allows it.

This is true.  The original work is still covered by the original
license.  What happens is a dual licensing, the original code is still
licensed under the BSD license, and the new code is licensed under the
GPL.

Only person who can re-license something is the copyright holder.
