From ec04aa3ae87b895dbc674a7e0b78b670f73a2c22 Mon Sep 17 00:00:00 2001 From: Markus Mayer Date: Wed, 27 Sep 2017 16:02:35 -0700 Subject: tools/thermal: tmon: use "-fstack-protector" only if supported Most, but not all, toolchains support the "-fstack-protector" flag. We check if the compiler supports the flag before using it. This allows tmon to be compiled for more environments.
