rfbsrc dependency on libX11 automagic
Submitted by Gilles Dartiguelongue
I haven't noticed this before but it looks like rfbsrc and eglglessink both depend on libX11 optionally.
The issue is that the dependency is automagic  and it makes a "dependency-less" plugin (rfbsrc) not so dependency-less according to build environment.
I would propose a patch but it looks like something already provides --with-x and I cannot figure out where it comes from yet.
