+  Xtensa relocations to mark the difference of two local symbols.
+  These are only needed to support linker relaxation and can be ignored
+  when not relaxing.  The field is set to the value of the difference
+  assuming no relaxation.  The relocation encodes the position of the
+  subtracted symbol so the linker can determine whether to adjust the field
+  value.  PDIFF relocations are used for positive differences, NDIFF
+  relocations are used for negative differences.  The difference value
+  is treated as unsigned with these relocation types, giving full
+  8/16 value ranges.
