Currently, all non-Android Linux hosts are assumed to be using glibc.
This obviously isn't very portable and will currently result in
downloading a stage0 toolchain for glibc even on musl hosts.
There are multiple ways to detect musl somewhat reliably, but the
easiest option is to check for the python SOABI config variable, which
has values like "cpython-313-x86_64-linux-gnu" or
"cpython-313-powerpc64-linux-musl".

use `realpath` in `bootstrap.py` when creating build-dir
Fixes#139800
r? `@jieyouxu`
My use case for `./build` being a symlink is this: my "default" ~~partition~~ btrfs subvolume is snapshotted/backed up. I don't want to backup target-likes, so I move them to a special subvolume which isn't backed up. `./build` is a symlink into that subvolume. (`build.build-dir` configuration is not fully sufficient, it is still nice to be able to check build files with `ls ./build` or call tools from there)
Replace black with ruff in `tidy`
`ruff` can both lint and format Python code (in fact, it should be a mostly drop-in replacement for `black` in terms of formatting), so it's not needed to use `black` anymore. This PR removes `black` and replaces it with `ruff`, to get rid of one Python dependency, and also to make Python formatting faster (although that's a small thing).
If we decide to merge this, we'll need to "reformat the world" - `ruff` is not perfectly compatible with `black`, and it also looks like `black` was actually ignoring some files before. I tried it locally (`./x test tidy --extra-checks=py:fmt --bless`) and it also reformatted some code in subtrees (e.g. `clippy` or `rustc_codegen_gcc`) - I'm not sure how to handle that.
explain the options bootstrap passes to curl
also fixes a discrepancy where the rust side doesn't use -L
docs are only on the rust side, since duplicated prose has a tendancy to get out-of-sync, and also because there are talks of removing the python script all together eventually.

handle stage0 `cargo` and `rustc` separately
This change allows setting either `build.cargo` or `build.rustc` without requiring both to be set simultaneously, which was not possible previously.
To try it, set `build.rustc` without setting `build.cargo`, and try to bootstrap on clean build.

Technically, wiping bootstrap builds can increase the build time.
But in practice, trying to manually resolve post-bump issues and
even accidentally removing the entire build directory will result
in a much greater loss of time. After all, the bootstrap build process
is not a particularly lengthy operation.

LLVM 18 now ships `libLLVM*.so.*`, so `.so` is not the sole extension
anymore, which breaks the dylib detection. Oops! Adjust it to only
search for `.so` somewhere.
Setting the bootstrap cache path to an external location can help to
speed up builds in cases where the build directory is not kept between
builds, e.g. in CI or other automated build systems.
This allows the bootstrap cache path to be set by the
`RUSTC_BOOTSTRAP_CACHE` environment variable.

Note that RUSTFLAGS_BOOTSTRAP should always be added to the end of
RUSTFLAGS to be actually effective (e.g., if we have `-Dwarnings` in
RUSTFLAGS, passing `-Awarnings` from RUSTFLAGS_BOOTSTRAP should override it).

warn if source is not either a git clone or a dist tarball
When the repository is downloaded directly via HTTP(as in #115041), builds may fail due to missing submodules.
This PR adds a check that warns people in such cases.
