I am not sure we want to do that. Indeed, Buildroot already has
top-level options to enable/disable various hardening features. We
don't want packages to randomly enable/disable such hardening features
solely based on SSP availability.

So I think we should keep hardening disabled from the point of view of
keepalived configure script, and let Buildroot pass the appropriate
CFLAGS/LDFLAGS through the wrapper.

Best regards,

Thomas
