FWIW it still fails at the final link step:
ld -m elf_x86_64 -o .tmp_vmlinux1 -T arch/x86_64/kernel/vmlinux.lds
arch/x86_64/kernel/head.o arch/x86_64/kernel/head64.o

ld:arch/x86_64/kernel/vmlinux.lds:383: parse error
make: *** [.tmp_vmlinux1] Error 1
Here are the relevant lines of arch/x86_64/kernel/vmlinux.lds:
382 OUTPUT_FORMAT("elf64-x86-64", "elf64-x86-64", "elf64-x86-64")
383 OUTPUT_ARCH(1:x86-64)
384 ENTRY(phys_startup_64)
Any ideas? Another toolchain quirk?
