From f2bd679c9dcd48a5ba3445f99524303bed9cf252 Mon Sep 17 00:00:00 2001 From: Carlos Santos Date: Thu, 22 Mar 2018 17:27:50 -0300 Subject: [PATCH] tpm2-abrmd: allow building without stack smashing protection (SSP) Disable SSP if the toolchain does not support it. This must be done explicitly because configure.ac passes -fstack-protector-all to the compiler but doesn't contain a link test, so it doesn't detect when libssp is missing.
