Genode 12.11 on Ubuntu 64 bits: Could not open file "ld.lib.so" seems to cause black window

[Paul Dufresne]

First, I did not search yet for issues showing this.
It is just a ... "hey, that's seems wrong, anyone knows about this?".

After my "make run/demo" on Linux Ubuntu 64 bits, I got a big black
window, that was empty so I closed it.

The log after compilation shows:

    COMPILE  launcher.o
