The question is whether we want SSP support to be enabled as soon as
the toolchain *has* SSP support, or only when the user explicitly
request SSP support using BR2_SSP_{REGULAR,STRONG,ALL} ?

This is a real policy decision:

 - Do we let the packages default to what they think is good (of course
   as long as the toolchain provides what's needed) ?

 - Or do we enforce the system-level configuration options that
   Buildroot has ?
