[PATCH] configure.ac: warn if stack-protector not allowed

[Nicholas Vinson]

Previous version of configure.ac would error out when
--enable-stack-protector was given and a selected GRUB platform did not
support the flag.  The new behavior is to warn that the flag is not
supported and force disable it for that platform.
