How are CPU-optimized libraries supposed to work?

[Daniel Jacobowitz]

I built an i386 ld.so and an i686 libc.so/libpthread.so, and put the latter
in /lib/i686.  It crashes in pthread_initialize, and I tracked the problem
down to this:

That's in struct rtld_global.  The linker doesn't think the timing offsets
are there, so pthread's access to the structure crashes.  So, two questions:

- This is supposed to work the way I'm doing it... right?
- Should the hp_timing members be moved, or should they be always provided
  for i386 in case i686 libs are used?
