Conditionally perform common relocation fixups
Add #ifdefs where necessary to not perform relocation fixups. This allows boards/architectures which support relocation to trim a decent chunk of code. Note that this patch doesn't add #ifdefs to architecture-specific code which does not support relocation. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
