4.8-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jan Beulich <JBeulich@suse.com>
commit a2209b742e6cf978b85d4f31a25a269c3d3b062b upstream.
Older GCC (observed with 4.1.x) doesn't support -Wno-override-init and also doesn't ignore unknown -Wno-* options.
