Stack protector has been added in version 3.0.3 by
https://github.com/lxc/lxc/commit/2268c27754152aa538db2c9e3753d72d19bcd17a

However, some compilers could missed the needed library (-lssp or
-lssp_nonshared) at linking step so use ax_check_link_flag instead of
ax_check_compile_flag

Changes v2 -> v3 (after review of Baruch Siach):
 - Add patch to use ac_check_link_flag

Changes v1 -> v2 (after review of Thomas Petazzoni):
 - Drop patch to add a new option, instead use
   ax_cv_check_cflags__Werror__fstack_protector_strong=no

Applied to master after updating the upstream status of the patch,
since it was applied. Thanks!

Applied to master, thanks. I think you could submit upstream, it's a
fix that makes sense to have.

Thanks!
