commit 3a8a047586 upstream.
Using -ffat-lto-objects in the python feature test when building with
clang-13 results in:
clang-13: error: optimization flag '-ffat-lto-objects' is not supported [-Werror,-Wignored-optimization-argument]
error: command '/usr/sbin/clang' failed with exit code 1
cp: cannot stat '/tmp/build/perf/python_ext_build/lib/perf*.so': No such file or directory
make[2]: *** [Makefile.perf:639: /tmp/build/perf/python/perf.so] Error 1
Noticed when building on a docker.io/library/archlinux:base container.

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.
