configure: Make stack-protector test check both compile and link
Since we use the -fstack-protector argument at both compile and link time in the build, we must check that it works with both a compile and a link: * MacOSX only fails in the compile step, not linking * some gcc cross environments only fail at the link stage (if they require a libssp and it's not present for some reason) Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Message-id: 1397232832-32301-1-git-send-email-peter.maydell@linaro.org Tested-by: Alexey Kardashevskiy <aik@ozlabs.ru>
