[PATCH] Set the host library path in run-make v2

When the build is configured with `[rust] rpath = false`, we need to set
`LD_LIBRARY_PATH` (or equivalent) to what would have been the `RPATH`,
so the compiler can find its own libraries. The old `tools.mk` code has
this environment prefixed in the `$(BARE_RUSTC)` variable, so we just
need to wire up something similar for run-make v2.

This is now set while building each `rmake.rs` itself, as well as in the
`rust-make-support` helpers for `rustc` and `rustdoc` commands. This is
also available in a `set_host_rpath` function for manual commands, like
in the `compiler-builtins` test.

[PATCH] Fix UI tests with dist-vendored dependencies

There is already a workaround in `compiletest` to deal with custom
`CARGO_HOME` using `-Zignore-directory-in-diagnostics-source-blocks={}`.
A similar need exists when dependencies come from the local `vendor`
directory, which distro builds often use, so now we ignore that too.

Also, `issue-21763.rs` was normalizing `hashbrown-` paths, presumably
expecting a version suffix, but the vendored path doesn't include the
version. Now that matches `[\\/]hashbrown` instead.

Fix get_toml() when cfg(test)

Bug: https://github.com/rust-lang/rust/issues/105766
Last-Update: 2023-03-29

When cfg(test), Config::parse doesn't parse a config.toml but uses default
values, failing when the initial rustc is needed. This is a workaround before
upstream issue gets solved.

[PATCH] tests: add missing cross disabled checks

cross_conmpile::alternate states it should only be used in test cases
after checking cross_compile::disabled(), which is missing here. these
tests fail despite setting CFG_DISABLE_CROSS_TESTS on i386, since both
the host and the alternate cross target would be i686 in that case.
