Suppress -fstack-protector warning on hppa.
Some package builds enable -fstack-protector and -Werror. Since -fstack-protector is not supported on hppa because the stack grows up, these packages must check for the warning generated by -fstack-protector and suppress it on hppa. This is problematic since hppa is the only significant architecture where the stack grows up. 2022-12-16 John David Anglin <danglin@gcc.gnu.org> gcc/ChangeLog: * config/pa/pa.cc (pa_option_override): Disable -fstack-protector. gcc/testsuite/ChangeLog: * lib/target-supports.exp (check_effective_target_static): Return 0 on hppa*-*-*.
