Looks like I need to 'make install' before I can use the translations? I
don't have any qemu version installed into the system, but always run it
from to build directory (I would only confuse the different trees if
something was installed). Shouldn't it be possible that qemu finds the
right files just like it does with the BIOS etc.?

- F10 still activates the menu (same for Alt-F/V)
