I suspect your OS bits don't include the c++ shared library bits
which are compatible with what came with 8.99.35, which is what
sits in my target root for evbarm64 on my "cross-build rust
bootstraps" host.

I could update my target root, but that would also force any
consumers to use newish NetBSD bits if they want to bootstrap
rust.  But since both are "-current" I guess that's not a big
problem, and I'll take a note behind my ear to bump my target
root OS version.
