-Mark the symbol as an indirect function when evaluated during reloc

+Mark the symbol as an indirect function.  This has the same semantics as
+STT_FUNC except when the symbol is referenced by a relocation.  In this case
+the symbol's value is not used in the relocation but instead the symbol is
+invoked as a function taking no arguments and the return value is used in the
+relocation.  This also means that processing of the relocation must be delayed
+until run-time.  (This is only supported on some targets).

 Note: Some targets support extra types in addition to those listed above.
