armv7 targeted editors/emacs@full build: sometimes "Hash table too large" and sometimes not

In a bulk -a -c attempt on aarch64 hardware that can execute
armv7 code, I'm using an armv7 poudriere jail to target armv7.
It got:

. . .
Loading replace...
Hash table too large
gmake[2]: *** [Makefile:584: emacs.pdmp] Error 255
gmake[2]: Leaving directory '/wrkdirs/usr/ports/editors/emacs/work-full/emacs-28.1/src'
gmake[1]: *** [Makefile:449: src] Error 2
gmake[1]: Leaving directory '/wrkdirs/usr/ports/editors/emacs/work-full/emacs-28.1'
===> Compilation failed unexpectedly.
Try to set MAKE_JOBS_UNSAFE=yes and rebuild before reporting the failure to
the maintainer.
*** Error code 1
. . .

But when I tried to do the build on another such machine it
built to completion.

(Both contexts are Cortex-A72 based but are otherwise rather
different.)
