i386: work around miscompilation of alternatives code
A recent change makes my Dell 1501 hang on boot. It's an AMD MK-36. I use
an x86_64 kernel. It is 100% reproducible.
I debugged this problem a bit and my compiler[1]interprets the =A constraint
as %rax instead of %edx:%eax on x86_64 which causes the problem. The appended
patch provides a workaround for this and fixed the hang on my machine.
