When debugging tests under GDB/valgrind there is a significant delay each time an execve is done as they scan shared libraries once again. For tests which use many mock libraries, we have been invoking execve many times which makes the debug experience horrible. This changes our framework to activate the full set of mock libraries in one single execve. Reviewed-by: Michal Privoznik <mprivozn@redhat.com> Signed-off-by: Daniel P. Berrangé <berrange@redhat.com>
