This is mostly required because of GCC 4.9 which seems
to error out with:
  openvswitch/datapath/linux/datapath.c:2108:10:
       error: macro "DATE" might prevent reproducible builds

We would have wanted to add '-Wno-error=date-time' directly
but that would be too specific, so we decided to add
a generic make flag and configure it with what we need.

This is from https://github.com/openvswitch/ovs/pull/18.  I'm posting it
here for review because I'm not the right person to review it and I'm not
sure that the OVS kernel maintainers are subscribed to the github issues
tracker.
