Hm, yes, I made the mistake of building the bootstrap on NetBSD
9.0_RC1.  I'll see if I can update the bootstrap to one built on
8.0.

As has been mentioned later here, this appears to be an instance of

  https://github.com/rust-lang/rust/issues/68714

and a workaround could be to add

# XXX: fix for Rust 1.41.0 https://github.com/rust-lang/rust/issues/68714
MAKE_ENV+=	LIBRARY_PATH=${BUILDLINK_PREFIX.llvm}/lib

as Adam wrote just now.

This is apparenty also seen by others, and reported in

  https://github.com/rust-lang/rust/issues/68794

which is now closed.  There's apparently some hope it'll be
included in rust 1.42.  I don't know how to pull the fix from
what's referred to from that issue, though, as it appears just to
refer to other git repositories, and I don't think there's a
"fetch code from other git repos" stage in the rust build we
do...
