From d77d8cc402e597bb38edfb4e81db89fd7d96d0b6 Mon Sep 17 00:00:00 2001
From: Adrian Reber <areber@redhat.com>

Subject: [PATCH] fix building with newer glibc
Newer glibc releases have removed SIGUNUSED from bits/signum.h which
breaks building criu on those systems:
https://sourceware.org/git/gitweb.cgi?p=glibc.git;a=commitdiff;h=8082d91e1c449e0cb137468b731004a5e605c8c6
SIGSYS returns the same value as SIGUNUSED and testing has shown
that criu still successfully completes zdtm with this patch.
