Dear all,

So, I updated the buildroot submodule properly and removed brltty as an
external package.

I am now facing another compile problem, with qemu I think:

I tried to disable the host qemu in make menuconfig but that was not
possible.

I also discovered that the host qemu seems to be selected by emacs but I
don't understand what's the linkbetween the two (emacs is provided in
the br2-external tree).

Any hint?

Thanks,

Sh?rab.
