commit b9c9ce4e598e012ca7c1813fae2f4d02395807de upstream. Python 3.8 changed the output of 'python-config --ldflags' to no longer include the '-lpythonX.Y' flag (this apparently fixed an issue loading modules with a statically linked Python executable). The libpython feature check in linux/build/feature fails if the Python library is not included in FEATURE_CHECK_LDFLAGS-libpython variable. This adds a check in the Makefile to determine if PYTHON_CONFIG accepts the '--embed' flag and passes that flag alongside '--ldflags' if so. tools/perf is the only place the libpython feature check is used.

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.
