To which tree?

This failure appears to be with 9.0.  IIRC, there have been fixes
to ld.elf_so related to thread-local storage after that, and
which are only present in 9.4 and onwards?

Although the error message doesn't seem to resemble what you get
when that fails.

I should perhaps admit that I've not tested NetBSD/x86_64 9.x
with rust.  Perhaps I should (have)...

I'm starting off a build on 9.3 to see if I can reproduce this,
and will possibly subsequently upgrade to 9.4 to see if that
fares any better.
