I looked up the Tegra K1: The armv7 variant T124 has
Cortex-A15's with LPAE (limited to 8 GiBytes). Does
FreeBSD do anything to support the LPAE? If yes, might
that lead to a larger maximum process size in FreeBSD?

Be that as it may, is there any chance that you could
use, say, top and watch llvm12's llc command's SIZE for
the:

  HC [stage 1] compiler/stage2/build/GHC/Hs/Instances.p_o

to see how large it grows? If it stays smaller than
2 GiBytes, that would indicate a different direction
of investigation than if it grows larger (the current
status of the investigation). Also, how large a SIZE
for a successful llc would be of interest itself.
