Log: Remove now redundand ifunc relocation code which should have been removed as part of r341441. This call to reloc_non_plt() may crash if ifunc resolvers use the needed libraries symbols since the pass over the needed libs relocation is not yet done. The change in r341441 ensures the right relocation order otherwise.
