Now that `RUSTC_VERSION_TEXT` exists, use it to rebuild `core` when the version text changes (which in turn will trigger a rebuild of all the kernel Rust code). This also applies to proc macros (which only work with the `rustc` that compiled them), via the already existing dependency on `core.o`. That is cleaned up in the next commit. However, this does not cover host programs written in Rust, which is the same case in the C side. This is accomplished by referencing directly the generated file, instead of using the `fixdep` header trick, since we cannot change the Rust standard library sources. This is not too much of a burden, since it only needs to be done for `core`.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
