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.

Otherwise something that ought to seemingly work like `//[x86]
needs-llvm-components: x86` or `//[nll_beyond]should-fail` do not get
evaluated properly.

Doesn't work though, because compiletest doesn't process ignores on a
per-revision manner.

- Suggest using `rustup target add` if `RUSTUP_HOME` is set. I don't know if there's any precedent for doing this, but it seems harmless enough and it will be a big help.
- Add a note about `#![no_std]` if `std` is missing but not core
- On nightly, suggest using `cargo build -Z build-std` if `CARGO` is set
- Add a note that std may be unsupported if `std` is missing but not core
- Don't suggest `#![no_std]` when the load isn't injected by the
compiler
