I had read this first and had tried to replace 1 
with 0 but then I found the following:
http://lists.gnu.org/archive/html/qemu-devel/2008-11/msg00990.html

I now tested compiling the following:
     __asm__ volatile(
         "0:\n"
         "mftbu  %2\n"
         "mftb   %0\n"
         "mftbu  %1\n"
         "cmpw   %2,%1\n"
         "bne    $-0x10\n"
