I had the exact same problem (gcc (GCC) 4.1.2 (Gentoo 4.1.2), GNU
assembler 2.16.1, GNU ld version 2.16.1).
As far as I can tell binutils is mostly broken for 16-bit code and
different versions of binutils is broken in different ways... ;-)
It's fairly easy to fix though - in "/arch/x86/stage0_i586.S" find the
first line with the "lgdt" instruction in it (it's about line number
60) and replace that line with these lines:
I'm not too sure if that's the only thing I messed with to get it to
work (but I think it is) - to be honest, I stumbled around doing all
sorts of things for a while first (I'm much more used to assemblers
like NASM, and much less familiar with "compiler back-ends pretending
to be assemblers")...
