Patch for coreutils 4.5.7 on Mac OS X

[Petter Reinholdtsen]

Hello

I had to apply the following patches to get coreutils 4.5.7 to compile
on Max os X.

If fixes the following problems

 - Make sure u_int32_t is available when <sys/dirent.h> needs it.

 - Correct #ifdef in code enabling UNAME_HARDWARE_PLATFORM and
   UNAME_PROCESSOR, to work around the fact that <sysctl.h> is missing
   on Mac OS X.  Why is <sys/param.h> protected by HAVE_SYSCTL_H?

 - Mac OS X is broken and to not return a sensible value for
   sysctl({CTL_HW,HW_MACHINE_ARCH}, ...).  Implemented workaround.  I
   need to make sure 'uname -p' return a sensible value to keep
   config.guess/configure happy when compiling some source.

Please include these patches in the next version of coreutils.
