Sorry, took a little while to test. Issue seems to be unchanged with
NetBSD-9/i386 (change builds fine on NetBSD-9/amd64)

Diff was just:
-.include "../../lang/llvm/buildlink3.mk"
+.include "../../lang/libLLVM/buildlink3.mk"

Still fails with:


running: /var/obj/pkg/lang/rust/work/rust-bootstrap/bin/cargo build
--manifest-path
/var/obj/pkg/lang/rust/work/rustc-1.38.0-src/src/bootstrap/Cargo.toml
--frozen
error: process didn't exit successfully:

1)

Interestingly forcing .buildlink/lib/libLLVM into LD_LIBRARY path
switches the failure to:

So... something building against a mismatched compiler?
