Until the link-vmlinux.sh split (cf. the commit below), the linker was run with jobserver set in MAKEFLAGS. After the split, the command in Makefile.vmlinux_o is not prefixed by "+" anymore, so this information is lost.
Restore it as linkers working in parallel (esp. the LTO ones) make a use of it.
