What is interesting is that the failure of "minidlna" due to "vaapi"
and "vdpau" options in "ffmpeg3" depends on the _installed package_
and not the current values of the various PKG*OPTIONS* variables.

With ffmpeg3 built and installed with "vaapi" and "vdpau" enabled (but
masked due to "-x11"), it does not matter if I add "-vaapi -vdpau" to
"PKG_OPTIONS.ffmpeg3".  Minidlna will claim that it requires X11 and
fail to build because "/usr/X11R6" was not found.

$ pwd
/x/pkgsrc/multimedia/ffmpeg3
$ make show-var VARNAME=PKG_DEFAULT_OPTIONS
pam ssl -x11 -cups -pulseaudio -alsa -dbus -gvfs -jack -arts
$ make show-var VARNAME=PKG_OPTIONS.ffmpeg3
fdk-aac gnutls opencore-amr opus rtmp x265 xcb -vaapi -vdpau
$ make show-var VARNAME=PKG_OPTIONS
ass bluray fdk-aac fontconfig freetype gnutls lame libvpx opencore-amr

 ass bluray fdk-aac fontconfig freetype gnutls lame libvpx opencore-amr
openssl opus rtmp theora vaapi vdpau vorbis x264 x265 xcb xvid


If I build and install "ffmpeg3" with explicit "-vaapi -vdpau" in
PKG_OPTIONS.ffmpeg3, it doesn't matter if I take them out (re-enble
them) again.  "minidlna" will not complain and proceed to build.
