Looks like binutils has changed how it handles that

waitkb:
        xorl    %ecx,%ecx
1:      jmp     2f
2:      jcxz    3f
3:      inb     $0x64,%al
        testb   $2,%al
        loopnz  1b
        ret

ie, change the jmp (and jcxz) 0 to jmp label with a temp label immediately
following. There are a few other jumps that will need to be modified
similarly. One in read_cmos and one in start:

        jmp     0                   # flush the instruction pipeline

(that's the one in start as it's a little harder to find)

HTH
