+From: Joe Konno <joe.konno@linux.intel.com>
+Date: Tue, 11 Feb 2020 14:15:42 -0800
+Subject: [PATCH] configure.ac: ax_add_fortify_source
+
+Use a maintained autoconf-archive macro to determine whether we need to
+add -D_FORTIFY_SOURCE=3D2, or if the underlying OS (or toolchain) has it
+baked in.
+
+Signed-off-by: Joe Konno <joe.konno@intel.com>

+Fixes:
+  aclocal: error: too many loops
+
+Upstream-Status: Backport from 2.12
