the ifunc spec i know about

https://sites.google.com/site/x32abi/documents

says

STT_GNU_IFUNC

      This symbol type is the same as STT_FUNC except that it always
      points to a function or piece of executable code which takes no
      arguments and returns a function pointer. [..]

this implies to me that ifunc resolver is not applicable to data.
