0efdfa1d62 Auto merge of #46941 - ScottAbbey:freebsd-build-update, r=alexcrichton
Re-do the FreeBSD cross-builds to use Clang and libc++. Fixes #44433

Reviving #45077, from @jld:

> The main goal here is to use FreeBSD's normal libc++, instead of
> statically linking the libstdc++ packaged with GCC, because that
> libstdc++ has bugs that cause rustc to deadlock inside LLVM.
>
> But the easiest way to use libc++ is to switch the build from GCC to
> Clang, and the Clang package in the Ubuntu image already knows how to
> cross-compile (given a sysroot and preferably cross-binutils), so the
> toolchain script now uses that instead of building a custom compiler.
>
> This also de-duplicates the build-toolchain.sh script.

#45077 was close but didn't quite make it.  I rebased @jld's work off the current `master` and started with that.

I was able to determine that this Travis error (https://github.com/rust-lang/rust/pull/45077#issuecomment-336029862) was ultimately caused by `src/librustc_llvm/build.rs` attempting to follow a wrong value in `LLVM_STATIC_STDCPP` (https://github.com/rust-lang/rust/pull/45077#issuecomment-352639456).

I looked at the downstream port for FreeBSD (https://svnweb.freebsd.org/ports/head/lang/rust/) and it seems like they do not use `--enable-llvm-static-stdcpp`.

Since `libc++` is included in the FreeBSD 10+ base system, we don't need to statically link it either?

So in b989428f7d I have set the FreeBSD build to not actually use `LLVM_STATIC_STDCPP`.

I was able to run `./src/ci/docker/run.sh` with both `dist-i686-freebsd` and `dist-x86_64-freebsd` successfully and in about 1 minute of testing it seemed like the dist-x86_64-freebsd results worked on a FreeBSD 11 system.

It should fix #44433, which seems to be affecting many potential users.  Also FreeBSD users should be able to `./x.py build` which should help anyone who wants to upstream fixes for FreeBSD.

Questions:

Does this approach seem to be the right way to go? Do we actually really want to statically link `libc++`? (I tried that here, but it ultimately ran into a roadblock on x86_64: https://github.com/rust-lang/rust/pull/45077#issuecomment-353293414)

Can we rewrite the comment here to be more clear about why some systems aren't going to actually use this option:
b989428f7d/src/bootstrap/compile.rs (L550-L553)

How does this affect users of older FreeBSD systems? It seemed like no one was complaining about using a 10.3 base version in the thread for #45077.  FreeBSD seems to only officially support 10.3, 10.4, and 11.x right now, do we have to consider older users? The `libc++` stuff came in for FreeBSD 10, older FreeBSD used `libstdc++`.

Looks like @alexcrichton was leading the discussion on the previous issue:

r? @alexcrichton

Let me know what I can do to help get this through.

720a4b53f5 Rollup merge of #46940 - EdSchouten:cloudabi, r=alexcrichton
Add support for CloudABI targets to the rustc backend.

CloudABI is a sandboxed UNIX-like runtime environment. It is a
programming environment that uses a capability-based security model. In
practice this means that many POSIX interfaces are present, except for
ones that try to access resources out of thin air. For example, open()
is gone, but openat() is present.

Right now I'm at the point where I can compile very basic CloudABI
applications on all four supported architectures (ARM and x86, 32 and 64
bits). The next step will be to get libstd to work. Patches for that are
outside the scope of this change.

Fixing Rust Moderation Team link in Code of Conduct

The [Code of Conduct](https://github.com/rust-lang/rust/blob/master/CODE_OF_CONDUCT.md) has two broken links to the Rust Moderation Team.
- The current link is https://github.com/rust-lang/rust/blob/master/team.html#Moderation. That happened because the link is relative.
- The link in this PR is https://www.rust-lang.org/team.html#Moderation-team. Note: at the moment this is redirected client-side to a language-specific page and loses the fragment identifier. rust-lang/rust-www#992 aims to correct that.

Follow up to #46924, fix massive spurious failure when starting docker

It seems using `fe80::/64` causes `docker start` to fail with "Address already in use". Try to change to a unique local address range instead.

`fe80::/64` is a link-local address (similar to `169.254.0.0/16` in IPv4). Let's try to use a random "private network" address to see whether that fixes things.
