An offset > 2^15 would exceed the range of an addi immediate on ppc64le. Thus, rather than add the offset after loading the TOC reference, have different tocloader functions for each (symbol, offset) pair. In this case, the linker can handle large offsets by changing the value of foo+offset@toc@ha accordingly.
