add upstream patch, to fix "__GNUC_MINOR is not defined" build error that

causes some ports depending on nss to fail. e.g. net-im/pidgin-sipe.
The patch is taken from https://bugzilla.mozilla.org/show_bug.cgi?id=702090

This patch will be part of the next nss release and can be removed with the next
update.
