From: "Daniel P. Berrange" <berrange at redhat.com>
This ought to fix the build if you have net/if.h but do
not have struct ifreq
* configure.ac: Check for struct ifreq in net/if.h
* src/util/virnetdev.c: Conditionalize to avoid use of
struct ifreq if it does not exist

dnl Our only use of libtasn1.h is in the testsuite, and can be skipped
dnl if the header is not present. Assume -ltasn1 is present if the
dnl header could be found.
