building 32bit binaries

[Christoph Egger <Christoph_Egger%gmx.de@localhost>]

Hi!

I'm about making xen-tools buildable on NetBSD/amd64.

The build currently stops at building the Xen firmware that is used
to run HVM guests.

I could work around this by copying elf_i386.xr from a NetBSD/i386 
installation into /usr/share/ldscripts/.

Can someone add elf_i386.xr to the standard distribution of NetBSD/amd64, 
please?
This should allow building 32bit binaries on NetBSD/amd64 out of the box.
