+       The amd64 kernel now requires a ld that supports ifunc to produce a
+       working kernel, either lld or a newer binutils. lld is built by default
+       on amd64, and the 'buildkernel' target uses it automatically. However,

+       binutils port/package). lld will soon be default, and this requirement
