This needs further investigations, please don't merge the patch.

I now ran into a case where enabling the qemuall override has a
potentially undesirable effect: in connman-conf.bb it is used to install
a special service which configures the wired connection so that it works
when booted under qemu.

In a nutshell, enabling "qemuall" seems to mean "this *will* run under
runqemu", and not "this *might* run under runqemu".

I'll change the meta-intel patch so that it does something useful for
running under qemu without the qemuall override. Getting the network up
might be tricky :-/
