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)
