Summary:                    ffmpeg did not build on x86_64; needs CFLAGS -fPIC
Description: 
I don't know if this is x86_64 specific or not but the error message
indicates it might be. I am including the abbreviated output(below) for
reference. 

The error message indicated that the -fPIC should be passed to gcc. I
looked at the BUILD for ffmpeg and found that the ''-fPIC '' is there but
apparently commented-out:

  #export CFLAGS="$CFLAGS -fPIC"

[snip]
I removed the comment mark and tried again(with -rc).  It built.

Perhaps the comment mark should be removed?

Filed under wrong project. Should be Lunar Linux.

I have added a BUILD.x86_64 file to the package. It seems that only this
arch need -fPIC flag. The normal x86 one don't need it. In fact the build
fails for it if this flag is set.
