Simplify even further the docs Makefile by moving rust build logic
to the wrapper.
After this change, running make on an environment with rust enabled
works as expected.
With CONFIG_RUST:
$ make O=/tmp/foo LLVM=1 SPHINXDIRS=peci htmldocs
make[1]: Entrando no diretório '/tmp/foo'
Using alabaster theme
Using Python kernel-doc
GEN Makefile
DESCEND objtool
CC arch/x86/kernel/asm-offsets.s
INSTALL libsubcmd_headers
CALL /new_devel/docs/scripts/checksyscalls.sh
RUSTC L rust/core.o
BINDGEN rust/bindings/bindings_generated.rs
BINDGEN rust/bindings/bindings_helpers_generated.rs
...
Without it:
$ make SPHINXDIRS=peci htmldocs
Using alabaster theme
Using Python kernel-doc
Both work as it is it is supposed to do.
After the change, it is also possible to build directly with the script
by passing "--rustodoc".
if CONFIG_RUST, this works fine:
$ ./tools/docs/sphinx-build-wrapper --sphinxdirs peci --rustdoc -- htmldocs
Using alabaster theme
Using Python kernel-doc
SYNC include/config/auto.conf
...
RUSTC L rust/core.o
...
If not, it will produce a warning that RUST may be disabled:
$ ./tools/docs/sphinx-build-wrapper --sphinxdirs peci --rustdoc -- htmldocs
Using alabaster theme
Using Python kernel-doc

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.
