PGI-14.10 for 32-bit targets fails in the same manner as 13.7, 13.9 and
13.10.

I believe the following inline x86 asm is correct and more robust than the
existing code that pgi appears to reject:

#elif defined(HWLOC_X86_32_ARCH)
  __asm__(
  "xchg %%ebx,%1\n\t"
  "cpuid\n\t"
  "xchg %%ebx,%1\n\t"
  : "=a" (*eax), "=S" (*ebx), "=c" (*ecx), "=d" (*edx)
  : "0" (*eax), "2" (*ecx));
#else
