+Subject: [PATCH] configure.ac: fix stack-protector detection
+
+Use AC_LINK_IFELSE instead of AC_COMPILE_IFELSE to check for
+stack-protector availability as some compilers could missed the needed
+library (-lssp or -lssp_nonshared) at linking step:

+# We're patching configure.ac

I've changed that to just list the patch that touches configue.ac. That
way, it is easier to notice to drop autoreconf when we drop the patch.

Applied to master, thanks.

Patch was for next as stated in commit title, not for master (perhaps
I should also have specified it in the commit message).

Regards,
Yann E. MORIN.
