Hmm, so commit 0630535e2d062dd73c1ceca5c6125c86d1127a49 is all about
removing code that is not used because these arches do not do any
relocation at all?

So ultimately, what we are looking at is the complete and utter
removal of any code which references a relocation adjustment in lieu
of each arch either:

  a) Execute in Place from Flash, or;
  b) Setting a fixed TEXT_BASE at a known RAM location and copying
     the contents of Flash to RAM, or;
  c) Implementing full Relocation
