[Qemu-devel] [PATCH] configure: linux-user doesn't need neither fdt nor slirp

[Laurent Vivier <lvivier@redhat.com>]

if softmmu is not enabled, we disable by default fdt and
slirp as they are only used by -softmmu targets.

A side effect is the git submodules are not cloned
if they are not needed.

Clone and build can be forced with --enable-fdt and
--enable-slirp.
