As of r333461 we require ifunc support to link a working amd64 kernel. The default in-tree bootstrap linker is lld and it has the required support, as does any modern out-of-tree binutils linker. The in-tree GNU ld is from binutils 2.17.50 and it does not have ifunc support, so produce an error rather than a broken kernel.
