I'd suggest you to comment
QEMU_OPT += -display sdl
out from the etc/build.conf, and add an option like
QEMU_OPT += -display vnc=<IP address>:<display>

This would activate QEMU built-in VNC server. You would be able to 
access the Genode display via a VNC client, connecting to a <IP 
address>:<display> VNC display.

I'm connecting to my development Linux system from my main OS, via SSH. 
When I need to run binaries, to test them, I start the corresponding run 
script. I see the logs in my SSH window. When I need to see the Genode 
screen, I just start the VNC viewer. The only disadvantage is that the 
mouse cursor in a VNC client is displaced, relative to Genode mouse 
cursor. I still did not worked this problem around. Also, there exists 
an option to run QEMU screen, or a SDL window in Genode/Linux, remotely 
via X11 remote connection (you need your DISPLAY env. variable to point 
to your local X11 display). But I did not managed to make it working 
successfully, because when I run it from an SSH session, it tries to use 
the "fbcon" SDL backend. Trying to set SDL_VIDEODRIVER env. variable to 
"x11" doesn't help here.
