Andreas reported that a specific build environment for an external module, being a bit broken, does pass CC_IMPLICIT_FALLTHROUGH quoted as argument to gcc, causing an error gcc-11: error: "-Wimplicit-fallthrough=5": linker input file not found: No such file or directory Until this is more generally fixed as outlined in [1], by fixing scripts/link-vmlinux.sh, scripts/gen_autoksyms.sh, etc to not directly include the include/config/auto.conf, and in a second step, change Kconfig to generate the auto.conf without "", workaround the issue by explicitly unquoting CC_IMPLICIT_FALLTHROUGH.

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.
