Well not sure we want to go down this road: it would mean we should add
host-qt as a dependency of the linux-xconfig target for example. We
could also decide that the *-menuconfig targets need to have curses-dev
installed on the build machine, but that the package that we build and
that need host-curses will depend on host-curses.

But well, menuconfig is indeed widely used, so maybe the easiest
solution would be to make ncurses-dev a mandatory dependency.

Cool! For now, only migrate your x86/x86-64 machines. Note that instead
of using your toolchain, it will be randomly chosing from the toolchain
configurations available at
http://autobuild.buildroot.org/toolchains/configs/. If you think there
is some useful configuration that is missing, let me know.

We'll work on moving the PowerPC machine at a later point (that will
require building a toolchain on it, and then putting it on
http://autobuild.buildroot.org/toolchains/tarballs/).

Thanks!

Thomas
