[Qemu-devel] [PATCH] configure: Don't exit until all errors have been detected

[Juan Quintela <quintela@redhat.com>]

Currently, it exits until each error, so if you are installing on a new
machine, it requires lots of configure runs until you get all the
dependencies that you need.  With this change, it shows all the errors
with the selected configured options.
