No.  I intentionally use the native version here (struct foo instead of
struct foo_arch) to catch possible inconsistencies.

Without this hunk, checker.c doesn't compile because checker.c is copmiled
by HOSTCC, not CC.

How about the following patch?
Since The first hunk of the previous patch was committed to
the staging tree, this might not apply cleanly though.

Looks ok to me.  The whole sanity check doesn't work anyway when
cross-compiling, so not trying to build it in the first place is fine.

The previous patch doesn't apply cleanly. 
Here is the updated one.

Applied, but adding a new 'middle' hook is unfortunate. Is there perhaps a
better name we could pick? Or perhaps Gerd has a better idea how to fit
ia64's needs?

Replied to the wrong patch email. I'm talking about your patch to the domain
builder of course! :-)

I excluded the change to mkchecker.py. Apart from Gerd commenting on it, it
looked dodgy to me too (I can't see why that logic would depend on
build-host architecture).
