Don't think so.
With this:

That great stream of assembler errors comes down to:
arch/i386/kernel/entry.S: Assembler messages:
arch/i386/kernel/entry.S:858: Error: open CFI at the end of file; missing .cfi_endproc directive
make[1]: *** [arch/i386/kernel/entry.o] Error 1
So there seems to be a missing startproc in there.

I get

Which is a bit mysterious.
Still, I expect that with a bit of fiddling this patch can be made to work
with older binutils. I also suspect there's actually something wrong with
it.
