I am wondering why for this one we are adding a sub-option and not
using automatic detection of BR2_PACKAGE_SPICE=y in the .mk file, like
you've done for VNC and usb-redir.

On the other hand, we do have already a bunch of sub-options to
configure Qemu. We're not very consistent here :/

I based the handling of the --enable-spice option off of an old
upstream attempt from Yann that I had found at
http://lists.buildroot.org/pipermail/buildroot/2012-December/063058.html
. I don't have a preference either way so let me know if you'd prefer
a suboption or have it automatically enabled if BR2_PACKAGE_SPICE is
enabled similarly to the other options I've added.

Thank you,
Jared

When vnc support is enabled, vnc suboption will try to detect automatically some
dependencies (like libpng see [1][2]).

vnc-sasl        SASL encryption for VNC server
vnc-jpeg        JPEG lossy compression for VNC server
vnc-png         PNG compression for VNC server

Either disable them explicitly or handle the optional dependencies.

How to enable systems emulation or user-land emulation without sub-options?
What about removing BR2_PACKAGE_QEMU_SDL and BR2_PACKAGE_QEMU_FDT options and
handle the dependencies automatically?

I guess we should enable spice only when spice package is enabled by the user
(automatic detection).

Romain

As discussed, I've dropped the sub-option, and simply made it an
implicit optional dependency. And applied, of course!

Thanks!
