Thanks for the tips from Clemens, Jeremy and you, this seems to be
working in an acceptable and reliable manner then:

if { ![catch { registry_active ffmpeg-devel }] } {
    default_variants +devel
}

ffmpeg and ffmpeg-devel almost have the same files (indeed, at some
point, ffmpeg-devel will become ffmpeg, I presume), so I don't think it
would be reliable, on the longer run, to check on a specific file.

registry_active is not documented in the guide, is there another source
of documentation for internal API that I should be aware of, other than
asking on the mailing list?
