poudriere cross-compile problem.

In the past I've used poudriere on an amd64 host (14.4) to build 
packages for my pfsense box (arm64.aarch64). In order to use the same 
git hash as netgate, I build my poudriere jails from a local source 
tree, e.g:

     zfs create -o mountpoint=/usr/src/16-CURRENT -o compress=lz4 
tank/16-CURRENT
     cd /usr/src
     git clone https://git.freebsd.org/src.git 16-CURRENT
     cd 16-CURRENT
     git checkout c215eef34550
     poudriere jail -x -c -j pfsense2607 -a arm64.aarch64 -m 
src=/usr/src/16-CURRENT -b

This workflow was briefly broken, for example to build with 44f3e9f7f6c9 
you had to apply these changes:

  
https://cgit.freebsd.org/src/patch/?id=8d5a11cd0137d3ad70f6b06e063ea91a776d510a
  
https://cgit.freebsd.org/src/patch/?id=38e5564ecef53064c984d086a040c01100023f40

It's my understanding that everything should be working again but I'm 
not finding that to be the case. When I try to build a package with this 
newly built jail I see:

However the older jails still work. This makes me suspect native-xtools 
is still not quite right (or something else has changed).

Any hints?
