[Qemu-devel] [PATCH] configure: add more detailed hint of old libfdt-dev missing libfdt_env.h

[john.liuli]

libfdt_env.h is missing in some stable installs (<1.3.0-3),
some released linux distributions(e.g. Ubuntu 12.04) depending
on it still complain missing libfdt even if already installed.
So give more detailed hint for such OS users.
