CI: Add LTO support to clang in dist-x86_64-linux

After rust-lang/cc-rs#1279, we attempt to pass `-flto=thin` to clang. In `dist-x86_64-linux`, we don't build clang with the `LLVMgold.so` library so this fails. This attempts to resolve this
First, pass the binutils plugin include directory to Clang, [which will build the library](https://github.com/llvm/llvm-project/blob/2d6d723a85c2d007b0359c206d66cd2e5a9f00e1/llvm/docs/GoldPlugin.rst#how-to-build-it)
Second, this library depends on the *version of libstdc++ that we built* specifically. However, despite both the RPATH and LD_LIBRARY_PATH pointing to `/rustroot/lib`, we incorrectly resolve to the system libstdc++, which doesn't load.
```
# LD_DEBUG=libs,files
      2219:    file=libstdc++.so.6 [0];  needed by /rustroot/bin/../lib/LLVMgold.so [0]
      2219:    find library=libstdc++.so.6 [0]; searching
      2219:     search path=/rustroot/bin/../lib/../lib        (RPATH from file /rustroot/bin/../lib/LLVMgold.so)
      2219:      trying file=/rustroot/bin/../lib/../lib/libstdc++.so.6
      2219:     search path=/usr/lib64/tls:/usr/lib64        (system search path)
      2219:      trying file=/usr/lib64/tls/libstdc++.so.6
      2219:      trying file=/usr/lib64/libstdc++.so.6
```

Using `LD_PRELOAD` causes it to correctly load the library

I think this is probably not the most maintainable way to do this, so opening to see if this is desired and if there's a better way of doing this

Pkgsrc changes relative to rust184:

Cargo

- [Stabilize higher precedence trailing flags]
  (rust-lang/cargo#14900)
- [Pass `CARGO_CFG_FEATURE` to build scripts]
  (rust-lang/cargo#14902)

Rustdoc
-----
- [Doc comment on impl blocks shows the first line, even when the
  impl block is collapsed] (rust-lang/rust#132155)

Compatibility Notes
-------------------
- [`rustc` no longer treats the `test` cfg as a well known
  check-cfg] (rust-lang/rust#131729),
  instead it is up to the build systems and users of
  `--check-cfg`[^check-cfg] to set it as a well known cfg using
  `--check-cfg=cfg(test)`.

  This is done to enable build systems like Cargo to set it
  conditionally, as not all source files are suitable for unit
  tests.

  [Cargo (for now) unconditionally sets the `test` cfg as a well known cfg]
  (rust-lang/cargo#14963).
  [^check-cfg]: https://doc.rust-lang.org/nightly/rustc/check-cfg.html

- [Disable potentially incorrect type inference if there are trivial
  and non-trivial where-clauses]
  (rust-lang/rust#132325)

- `std::env::home_dir()` has been deprecated for years, because it
  can give surprising results in some Windows configurations if the
  `HOME` environment variable is set (which is not the normal
  configuration on Windows). We had previously avoided changing its
  behavior, out of concern for compatibility with code depending on
  this non-standard configuration. Given how long this function has
  been deprecated, we're now fixing its behavior as a bugfix. A
  subsequent release will remove the deprecation for this function.

- [Make `core::ffi::c_char` signedness more closely match that of
  the platform-default `char`]
  (rust-lang/rust#132975)

  This changed `c_char` from an `i8` to `u8` or vice versa on many
  Tier 2 and 3 targets (mostly Arm and RISC-V embedded targets).
  The new definition may result in compilation failures but fixes
  compatibility issues with C.

  The `libc` crate matches this change as of its 0.2.169 release.

- [When compiling a nested `macro_rules` macro from an external
  crate, the content of the inner `macro_rules` is now built with
  the edition of the external crate, not the local crate.]
  (rust-lang/rust#133274)
- [Increase `sparcv9-sun-solaris` and `x86_64-pc-solaris` Solaris
  baseline to 11.4.]
  (rust-lang/rust#133293)
- [Show `abi_unsupported_vector_types` lint in future breakage reports]
  (rust-lang/rust#133374)
- [Error if multiple super-trait instantiations of `dyn Trait` need
  associated types to be specified but only one is provided]
  (rust-lang/rust#133392)
- [Change `powerpc64-ibm-aix` default `codemodel` to large]
  (rust-lang/rust#133811)

Internal Changes
----------------

These changes do not affect any public interfaces of Rust, but they
represent significant improvements to the performance or internals
of rustc and related tools.

- [Build `x86_64-unknown-linux-gnu` with LTO for C/C++ code (e.g., `jemalloc`)]
  (rust-lang/rust#134690)
