I think this should probably be the final patch in the series, rather than the
first. It's generally best to set up all requirements first before enabling things
in the compile time configuration. Once this patch is added, there is a non-functional
target added for tile architecture. If it's added last, the moment the compile
time config is added it works correctly.

Agreed, this should be last.  Also, just for clarity, you're posting this very
close to the 1.8 release.  I presume your intent is to add this in for the 2.0
release, correct?

Fair point.  Thanks.

We'll reorder in the next version of this series.

Thanks
