GNU Make 3.81 fails in CONFIG_RUST=y builds. rust/Makefile:105: *** multiple target patterns. Stop. make[1]: *** [prepare] Error 2 make: *** [__sub-make] Error 2 The error message is unclear, but the reason is because the 'private' keyword is only supported since GNU Make 3.82. GNU Make 3.81 is still able to build the kernel when CONFIG_RUST is disabled, but it might be a good timing to raise the minimal GNU Make version. Perhaps, I am the last person who was testing GNU Make 3.81. GNU Make 3.81 was released in 2006, GNU Make 3.82 in 2010.

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.
