rust build failure on 8.99.36

[Thomas Klausner <wiz%NetBSD.org@localhost>]

Hi!

On an 8.99.36/amd64 (with the old c++ library still installed) I see a
new rust build failure:

To learn more, run the command again with --verbose.

When I restart the build, I get the same error. Also after a 'make
clean'.

Any ideas?
