Are you sure about the "enabled by default" ? There is not "default y"
here, is it?

Also I'm not sure whether it's such a good idea to always disable the
config switches in default-configs/arm-softmmu.mak ... if somebody wants
to build such a restricted QEMU, don't they have to maintain their own
set of config files anyway?

I think we should maybe rather rework the default-configs directory:
Rename the default to "config/default/" instead and then we can add
other subfolders with such special configurations, e.g. config/nemu/ or
config/lean-kvm/ or however you want to call it. Then add a new switch
to the configure script to be able to use the configs from such a
different folder.
