+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.
