Reuse CrateNum for proc-macro crates even when cross-compiling Proc-macros are always compiled for the host, so this should be the same in every way as recompiling the crate. I am not sure why the previous code special-cased the target, since the compiler properly gives an error when trying to load a crate for a different host: ``` error[E0461]: couldn't find crate `dependency` with expected target triple x86_64-unknown-linux-gnu --> /home/joshua/rustc4/src/test/ui/cfg-dependent.rs:8:2 | LL | dependency::is_64(); | ^^^^^^^^^^ | = note: the following crate versions were found: crate `dependency`, target triple i686-unknown-linux-gnu: /home/joshua/rustc4/build/x86_64-unknown-linux-gnu/test/ui/cfg-dependent/auxiliary/libdependency.so ``` I think another possible fix is to remove the check altogether. But I'm not sure, and this fix works, so I'm not making the larger change here.
