LICENSE: correct incorrect claims on *GPL incompatibility

There are currently no statements from any person qualified in the art
of law about the LGPL compatibility of the libfaac license and others.
Furthermore their is no consensus about their compatibility amongth
people not qualified in the art.

Also of interrest may be that ubuntu distributes and links libfaac
to LGPL code. And the ubuntu technical comittee decision about libfaac

Comments and other viewpoints, especially if i have missed something
are very welcome!
