Suppress -fstack-protector warning on hppa.

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.
