devel/llvm13 build: "ninja: build stopped: subcommand failed"

This was using poudriere, on a real amd64 machine with:

Aug 12 04:13:35 freebeast kernel: avail memory = 200736665600 (191437 MB)

in both:

I was out-of-town (and largely without Internet access) from 22 July to
05 August.  Prior to that, I don't recall issues building llvm in
poudriere on that machine -- nor do I encounter errors building it with
portmaster on my laptops (it just takes forever and a day!).

I only use llvm ports as dependencies of other ports, so I haven't
attempted to tweak the port configuration at all.

As things currently stand, the llvm13 build failure is causing poudriere
to "skip" building 42 ports (in each of stable/12 & stable/13) -- one of
which is www/chromium.

What sort of evasive action might be useful?

Thanks!

Peace,
david
