Thomas Weißschuh ffb569d59c tools/docs: sphinx-build-wrapper: only generate rust docs when requested
When the user explicitly specifies SPHINXDIRS to build a specific
subdirectory it is unexpected that the rust docs are also generated.
Especially as their generation may dominate the execution time.

Only generate the rust docs when they are part of the SPHINXDIRS
requested by the user. 'rust/rustdocs' is not considered, as it is
not a valid SPHINXDIRS anyways.

Linux kernel
============

The Linux kernel is the core of any Linux operating system. It manages hardware,
system resources, and provides the fundamental services for all other software.

Quick Start
-----------

* Report a bug: See Documentation/admin-guide/reporting-issues.rst
* Get the latest kernel: https://kernel.org
* Build the kernel: See Documentation/admin-guide/quickly-build-trimmed-linux.rst
* Join the community: https://lore.kernel.org/

Essential Documentation
-----------------------

All users should be familiar with:

* Building requirements: Documentation/process/changes.rst
* Code of Conduct: Documentation/process/code-of-conduct.rst
* License: See COPYING

Documentation can be built with make htmldocs or viewed online at:
https://www.kernel.org/doc/html/latest/
