[PATCH 1/3] pc-bios/optionrom: Add -fno-stack-protector

[Akihiko Odaki]

A build of GCC 13.2 will have stack protector enabled by default if it
was configured with --enable-default-ssp option. For such a compiler,
it is necessary to explicitly disable stack protector when linking
without standard libraries.
