Ok, so in module_64.c, under what cases is .toc NOT needed?

I dug at the code, and the R_PPC_REL24 blocks need the contents of the
.toc (via stub_for_addr -> create_stub -> my_r2), and I'm not certain
about it.

The R_PPC64_TOC/R_PPC64_TOC16/R_PPC64_TOC16_DS blocks shouldn't be hit
when there isn't a .toc* from what I figure.

If the R_PPC_REL24 block won't be hit when there isn't a .toc, the check
in module_frob_arch_sections, lines 194-197 can just be shortened as a
fix to the problem.
