new utrace patch breaks ia64

[Roland McGrath]

Thanks for catching that.  There were two issues (at least).

I fixed the missing #include you found.  Thanks.

The new code is not supposed to be enabled for ia64, because some of the
arch bits are still missing.  I thought I'd done that in config-ia64,
but I hadn't done the magic quite right.

I checked in an update to the patches and configs.  Please let me know if
the current cvs sources build on ia64.


Thanks,
Roland
