Make sure to clear out the stageN-{rustc,std,tools} directories.
We copy built tool binaries into a dedicated directory to avoid deleting them,
stageN-tools-bin. These aren't ever cleared out by code, since there should be
no reason to do so, and we'll simply overwrite them as necessary.
When clearing out the stageN-{std,rustc,tools} directories, make sure to delete
both Cargo directories -- per-target and build scripts. This ensures that
changing libstd doesn't cause problems due to build scripts not being rebuilt,
even though they should be.
Fixes https://github.com/rust-lang/rust/issues/44739.
rustbuild: fix dist in debug mode
In debug mode, the artifacts are placed in "debug", so don't hardcode "release" and use our helper to get the right directory name
Allow passing a path with tilde to the configure script
Currently `./configure --local-rust-root=~/.cargo --enable-local-rebuild` fails with
```
Exception: no cargo executable found at `~/.cargo//bin/cargo`
```
Remove --enable-rustbuild config option from an example
`--enable-rustbuild` is no longer recognized by the configure script. Also I think we should use `./configure` and `./x.py` instead of `configure` and `../x.py`.

While the `config.toml.example` comments say "we automatically check the
version by default," we actually didn't. That check was badly out of
date, only allowing 3.5, 3.6, or 3.7. This it now updated to the new
3.9 minimum requirement, and truly enabled by default.
This commit enables configuring the RLS/rustfmt tools to the "broken" state and
actually get it past CI. The main changes here were to update all dist-related
code to handle the situation where the RLS isn't available. This in turn
involved a homegrown preprocessor-like-function to edit the configuration files
we pass to the various combined installer tools.
Add x86_64-unknown-linux-gnux32 target
This adds X32 ABI support for Linux on X86_64. Let's package and dist it so we can star testing libc, libstd, etc.

Enable building clippy in CI
r? @alexcrichton
As discussed at Rustfest. Measured additional time is 4 minutes on my machine if no dependencies are shared with other tools. In reality most dependencies are shared (especially the slow to compile ones like serde).
cc @Manishearth
Does not run clippy's test suite, since
a) it is nontrivial in the rustc build system
b) it breaks more frequently but the breakage is negligible
If clippy breaks, the procedure to follow is documented under https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md#external-dependencies
rustdoc is built separately to rustc now so the docs would need to be
generated separately as well. Also rustdoc doesn't build at stage 1
which prevented the compiler docs being built at stage 1.
rustbuild: Prevent spurious rebuilds of the RLS
The RLS currently is rebuilt every time you test it because the `OPENSSL_DIR`
env var is changing, which is in turn caused by an accidental omission of
`prepare_tool_cargo` when testing the RLS.
incr.comp.: Bring back output of -Zincremental-info.
This got kind lost during the transition to red/green.
I also switched back from `eprintln!()` to `println!()` since the former never actually produced any output. I suspect this has to do with `libterm` somehow monopolizing `stderr`.

Fix PEP8 style issues in bootstrap code
This fixes PEP8 style issues (other than line-length) in the bootstrap Python code.
The most important fix is in the `set` function where the code was indented with 6 spaces instead of 4.
let rustdoc print the crate version into docs
This PR adds a new unstable flag to rustdoc, `--crate-version`, which when present will add a new entry to the sidebar of the root module, printing the given version number:
Closes#24336
(The WIP status is because i don't want to merge this until i can get the std docs to use it, which i need help from rustbuild people to make sure i get right.)

1. Add -f flag to curl, so when the server returns 403 or 500 it will fail
immediately.
2. Moved the checksum part into the retry loop, assuming checksum failure
is due to broken download that can be fixed by downloading again.
Fix path to x.py in bootstrap/configure.py script
We may see a help message in the end of the output of the ./configure script:
```
$ ./configure
configure: processing command line
configure:
configure: build.configure-args := []
configure:
configure: writing `config.toml` in current directory
configure:
configure: run `python ./src/bootstrap/x.py --help`
configure:
```
but the `x.py` script is actually in the rust root directory and
executing of such help string will give us error:
```
$ python ./src/bootstrap/x.py --help
python: can't open file './src/bootstrap/x.py': [Errno 2] No such file
or directory
```

Use identity operator `is` when comparing to None
This is very minor, but idiomatic Python code uses `is` for comparisons to `None`. This is because semantically we want to compare to the "identity" of `None`, not its value.
See [PEP8 for details](https://www.python.org/dev/peps/pep-0008/#programming-recommendations).
Fix variable name reference
As best I can tell, this was a typo due to how similar it looks to the function above it. PyCharm found this as a unbound local variable.
