commit b1fbfcb4a20949df08dd995927cdc5ad220c128d upstream.
Commit 2dffd23f81a3 ("kbuild: make single target builds much faster")
made the situation much better.
To improve it even more, apply the similar idea to the top Makefile.
Trim unrelated directories from build-dirs.
The single build code must be moved above the 'descend' target.

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 Restructured Text 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.
