Some investigation:
This depends heavily on the command line used.
A simple test with a hello world works.
On my kernel build when I strip the lto link command line down I get
the error with
gcc47 -fdump-cgraph-ipa -nostdlib -fuse-linker-plugin -flto=jobserver
-fwhole-program -Wl,-m,elf_x86_64 -Wl,--build-id -o .tmp_vmlinux1
-Wl,-T,arch/x86/kernel/vmlinux.lds arch/x86/kernel/head_64.o
arch/x86/kernel/head_64.o
and not with (last file deleted)
gcc47 -fdump-cgraph-ipa -nostdlib -fuse-linker-plugin -flto=jobserver
-fwhole-program -Wl,-m,elf_x86_64 -Wl,--build-id -o .tmp_vmlinux1
