This is rude as the caller may be using a different section. So let the caller decide which section to emit the code into. On big endian we do need to switch to the ".opd" section to emit the OPD, but do that with pushsection/popsection, thereby leaving the original section intact. I verified that the order of all entries in System.map is unchanged after this patch. The actual addresses shift around slightly so you can't just diff the System.map.
