Flatpak build summary is here:
https://buildd.debian.org/status/logs.php?pkg=flatpak&arch=hppa

In the recent successful builds on panama, it seems bwrap fails and the 
tests were skipped.
The bell and physik buildds have more memory (8 and 12 GB, respectively).

I doubt the age of the kernels is the problem as current upstream 
kernels (e.g., v4.13.x)
run on hppa.
