Currently there is no way to check that, show_banner() only shows
compile-time versions, while show_version() prints again the
compile-time versions, with the only exception the lavc version (which
is printed using the deprecated avcodec_build()).

So do you want to print both in show_banner() and in show_version()
both compile-time and link-time/run-time libs versions?
