IANAL, but AFAIK it is illegal to add clauses to the LGPL, except for 
geographical distribution limitations. The license text is copyrighted and 
may not be changed or extended with extra clauses. This is on purpose, to 
avoid having tons of slightly varying and possibly incompatible LGPL 
variations around. So something is either LGPL or it's not. Something can 
not be LGPL for just one project and GPL elsewhere.

As the author/copyrightholder does not want to license his code under the 
LGPL, the only valid option is the GPL.
