Commit852faf8055("gcc-plugins: remove SANCOV gcc plugin") removes the config CC_HAS_SANCOV_TRACE_PC, as all supported compilers include the compiler option '-fsanitize-coverage=trace-pc' by now. The commit however misses the important use of this config option in Makefile.kcov to add '-fsanitize-coverage=trace-pc' to CFLAGS_KCOV. Include the compiler option '-fsanitize-coverage=trace-pc' unconditionally to CFLAGS_KCOV, as all compilers provide that option now.

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.
