Sorry, i am running 9 STABLE with a clean pkgsrc-2020Q2, building
everything from there.

I have now installed compat_80 as suggested and rust-1.43.1nb1 started
to compile without the error.

So i guess the error should pop up on all architectures when using a
fresh NetBSD 9 install that has not seen NetBSD 8 before l?
