Thanks Keir. It doesn't work for me at the moment (including the ia64
follow-on patch) because it uses a custom ld script, tools/ioemu/ia64.ld
Here is the output when using that script. You can see pretty easily
that it's ignoring the sys-root. Jump down for a patch that fixes
this particular issue...

Here's a small patch which reduces this output significantly by fixing
the sys-root problem. It seems that the '=' tells ld to use the
sys-root, if it was built with --with-sysroot:

However even with this patch, the build still fails. I guess I need
to understand the point of these custom ld-scripts... With it
commented out in Makefile.target, the build works fine!
