If you go to line 1412 of the file xen/arch/arm/domain_build.c and
replace the "return res;" with "continue;" that will bypass the issue.
The 3 people I'm copying on this message though may wish to ask questions
about the state of your build tree.

Presently the rpixen script is grabbing the RPF's 4.19 branch, dates
point to that last being touched last year.  Their tree is at
cc39f1c9f82f6fe5a437836811d906c709e0661c.
