4.3 build failure in driver-i386.c

Hi,

This is on an ancient distro (don't ask..) i.e. RedHat 6.2. (4.2.3 builds
fine so this is somewhat of a regression...)

Looking at the -save-temps output, it seems the old assembler is choking
on this syntax from __get_cpuid_max() in cpuid.h:

.stabn 68,0,91,.LM210-__get_cpuid_max
.LM210:
#APP
        pushf{l|d}
        pushf{l|d}
        pop{l}  %eax
        mov{l}  {%eax, %edx|%edx, %eax}
        xor{l}  {$2097152, %eax|%eax, $2097152}
        push{l} %eax
        popf{l|d}
        pushf{l|d}
        pop{l}  %eax
        popf{l|d}

#NO_APP


It's kind of unfortunate for the build to break in this way. Is there any
hope for some kind of fix or workaround? I realize ancient distros are not
a priority, but still....

Thanks
