Thanks.
So you are confirming my poudriere is running an ARM compiler to produce 
ARM code?

What's the use of "-x" when creating a jail then?
What role does the "native cross-toolchain" play?
I understood that would mean running an AMD64 compiler to cross-build 
ARM code... and thought that its timings would be comparable to native 
building.
Is that wrong?

  bye & Thanks
