You can check config.log to see what was disabled. If you are getting no
ffplay, then check the line ``USE_SDL='' to see if that has anything.

To make sure SDL gets enabled, you'll want to set the environment
variable ``USE_SDL'' to ``/path/to/sdl-config''. Passing the output of
that to configure is a nightmare you don't want.

I had the entire build process (from git pull to install) in a script
and noticed that ffplay hadn't been updated in a month, and that fixed it.
