From 2909bfbc97559cf3e28c9045f64e3078aacca354 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Sat, 4 Apr 2015 17:59:32 +0200 Subject: [PATCH] configure.ac: use CC instead of gcc, full link for stack protector test Using gcc directly is incorrect when cross-compiling, $CC should be used instead. Also, for the stack protector test, a full link is needed, since just the compilation can work, but the link can fail due to libssp not being available in the toolchain.
