rust 1.42 fails to compile on NetBSD 9.0/amd64

[Jörn Clausen <joernc%googlemail.com@localhost>]

I just tried to to compile Firefox, but the build fails in lang/rust with

   Compiling rustc-main v0.0.0
(/export/wd0/pkgtemp/lang/rust/work/rustc-1.42.0-src/src/rustc)
error: linking with `cc` failed: exit code: 1
