Great.

  Andrew> x86_64 is not happy:

OK, looks like I failed to remove WANT_STAT64.

  Andrew> sparc64 is not happy:

Ah, __sparc__ is defined even for sparc64, makes sense, but I didn't
account for it.

The attached patch should have these fixed.

	--david

Below is a patch that tries to sanitize the dropping of unneeded
system-call stubs in generic code.  In some instances, it would be
possible to move the optional system-call stubs into a library routine
which would avoid the need for #ifdefs, but in many cases, doing so
would require making several functions global (and possibly exporting
additional data-structures in header-files).  Furthermore, it would
inhibit (automatic) inlining in the cases in the cases where the stubs
are needed.  For these reasons, the patch keeps the #ifdef-approach.

This has been tested on ia64 and there were no objections from the
arch-maintainers (and one positive response).  The patch should be
safe but arch-maintainers may want to take a second look to see if
some __ARCH_WANT_foo macros should be removed for their architecture
(I'm quite sure that's the case, but I wanted to play it safe and only
preserved the status-quo in that regard).
