+Subject: [PATCH] src: use getauxval in node_main.cc
+
+This commit suggests using getauxval in node_main.cc.
+
+The motivation for this is that getauxval was introduced in glibc 2.16
+and looking at BUILDING.md, in the 'Platform list' section, it looks
+like we now support glibc >= 2.17 and perhaps this change would be
+alright now.
