Teach bootstrap install and dist commands about TargetSelection
With this, we can now use a target JSON file to build a
cross-compiler:
```
x.py install --host ../aarch64-apple-darwin.json --target aarch64-apple-darwin
```

`rustc` allows passing in predefined target triples as well as JSON
target specification files. This change allows bootstrap to have the
first inkling about those differences. This allows building a
cross-compiler for an out-of-tree architecture (even though that
compiler won't work for other reasons).
Even if no one ever uses this functionality, I think the newtype
around the `Interned<String>` improves the readability of the code.

The current plan is that submodule tracks the `release` branch of
rust-analyzer, which is updated once a week.
rust-analyzer is a workspace (with a virtual manifest), the actual
binary is provide by `crates/rust-analyzer` package.
Note that we intentionally don't add rust-analyzer to `Kind::Test`,
for two reasons.
*First*, at the moment rust-analyzer's test suite does a couple of
things which might not work in the context of rust repository. For
example, it shells out directly to `rustup` and `rustfmt`. So, making
this work requires non-trivial efforts.
*Second*, it seems unlikely that running tests in rust-lang/rust repo
would provide any additional guarantees. rust-analyzer builds with
stable and does not depend on the specifics of the compiler, so
changes to compiler can't break ra, unless they break stability
guarantee. Additionally, rust-analyzer itself is gated on bors, so we
are pretty confident that test suite passes.

PR #49778 introduced fs::canonicalize() which fails for a nonexistent path.
This is a surprise for someone used to GNU Autotools' configure which can create any necessary intermediate directories in prefix.
This change makes it run fs::create_dir_all() before canonicalize().

although, not sure why this works - it wasn't needed before
|
|
This ensures that the failure cases for finding the codegen backend and
for finding the rustc binary are essentially the same, and since we
almost always will load the codegen backend, this is essentially meaning
that the rustc change is not a regression.
|
|
Make sure we look for save analysis in the right place. Fixes #61703.

This extends a test in the previous commit to assert that we don't build
extra rustc compilers even when the "extended" option is set to true.
This involved some internal refactoring to have more judicious usage of
`compiler_for`, added in the previous commit, as well.
Various `dist::*` targets were refactored to be parameterized with a
`Compiler` instead of a `stage`/`host`, and then the various parameters
within the `Extended` target were tweaked to ensure that we don't ever
accidentally ask for a stage2 build compiler when we're distributing
something.

rustbuild: pass datadir to rust-installer
This fixes zsh completion install when $datadir != $prefix/share
|
|
All uses are replaced with not accessing run.target/run.host, and
instead directly using run.builder.build.build.
|
|
All cases where it is used can be replaced by substituing run.host for
run.builder.build.build; that is its only effect. As such, it is
removable.

rustbuild: don't try to install rls if ToolState is not Testing
We already do that for the Dist Step so we would end up trying to install something that we didn't dist.
|
|
This fixes cross-compile installation. Half of the logic is actually in there
already in install.rs:install_std but it fails with an error like:
sh: 0: Can't open /<<BUILDDIR>>/rustc-1.21.0+dfsg1/build/tmp/dist/rust-std-1.21.0-powerpc64le-unknown-linux-gnu/install.sh
because the target-arch dist tarball wasn't built as well.
|
|
The Dist Step is not ran in that case so we would end up trying to
install something that we didn't dist.

The default install used to include rustc, rust-std, and rust-docs, but
the refactoring in commit 6b3413d825fa6 make rustc only default in
extended builds. This commit makes rustc installed by default again.
|
|
This introduces a slight change in behavior, where we unilaterally
respect the --host and --target parameters passed for all sanity
checking and runtime configuration.
|
|
|
|
|
|
Utilized primarily to not be a default rule unless some configuration is
given (e.g., compiler docs are enabled).
