[PATCH] Rework to minimize and eventually eliminate RTEMS use of bsp_specs

Hey Joel!

I'm not sure if this ever made it upstream - if it did, could you dig
the commit up?

I'll leave the x86_64's bsp_specs empty and make the RSB backporting
patches accordingly. If not, no rush, we should just add a ticket or
something so as to not lose track of it entirely after GSoC ends.
