[FFmpeg-devel] [RFC] libfdk_aac license

doc/general.texi says this for the FDK AAC library,

"The Fraunhofer AAC library is licensed under a license incompatible to 
the GPL and is not known to be compatible to the LGPL. Therefore, you 
have to pass @code{--enable-nonfree} to configure to use it."

(added 2013 in 6fe419bf73)

LICENSE.md says,

"The Fraunhofer FDK AAC and OpenSSL libraries are under licenses which 
are incompatible with the GPLv2 and v3. To the best of our knowledge, 
they are compatible with the LGPL."

(added 2016 in bbf7500df99)

Indeed, current master can be configured and built as LGPL with FDK AAC 
without passing --enable-nonfree even though the lib is in the nonfree 
list. configure only complains about nonfree if I set license as GPL.

If this is how it should be, I'll update general.texi
