uname -m and uname -p

[n a]

Looking at uname.c (which is part of the GNU coreutils) where it handles the
-p, here is some code:

-----
char const *element = unknown;
#if HAVE_SYSINFO && defined SI_ARCHITECTURE
{
  static char processor[257];
  if (0 <= sysinfo (SI_ARCHITECTURE, processor, sizeof processor))
    element = processor;
}
#endif
------

The problem is that HAVE_SYSINFO and SI_ARCHITECTURE are never defined
anywhere, at least not in my standard Edgy kernel. Doing a google search,
this looks like it has been broken for some time. There have been many
patches proposed, but none have actually been applied. Gentoo seems to have
their own patch for it though.
