[libvirt] [PATCH 01/11] Fix possible undefined value in check-symsorting.pl

[Daniel P. Berrange]

From: "Daniel P. Berrange" <berrange at redhat.com>

It is possible for $line to be undefined at first used, if
the symfile doesn't have a section prefix (which is the case
for auto-generated symfiles).
