Re: llvm10 build failure on Rpi3

[freebsd-arm+owner at sent a notice of rejection
of the original of the below because, according to it, I was
not a subscriber to freebsd-arm. So this is a resend after
(re-)subscribing. We will see if it is again rejected.]

No failure.

In a faster context with RAM such that there is no reported
use of swap in top, I've tried a host kernel that is non-debug
and a host kernel that is debug in combinations with host
worlds that are non-debug vs. debug in combination with systems
for the jail that are non-debug releng/13 based, non-debug
main based, and debug main based.

So far none of that has failed.

On the RPi4B with total_mem=1024 I've only had the non-debug
main host kernel and world and a world for jail use that was
nondebug. But I've tried with and without junk:true.

No failures.

For the RPi4B, I've now got a debug host kernel and world
and a debug world for jail use. So, by default, junk:true .

We will see if it gets a failure or not.

It is likely the last of the reproduction attempts based on
the information so far.
