Yes, that's exactly what I was (cryptically) saying.  Existing object
files for these targets may already be using 255.  The following
appear to be available according to my scan over include/elf/*.h: 142,
143, 152, 155, 156, 157, 159, 197, 198, 199, 202, 203, 204, 205, 206,
207, 208, 209, 210, 211, 212, 213, 214, 215, 217, 218, 225, 226.
Perhaps it might be better to define the reloc on a target by target
basis?
