Builds started failing in Fedora on Python 3.7 with:
`.gnu.debuglto_.debug_macro' referenced in section
`.gnu.debuglto_.debug_macro' of
util/scripting-engines/trace-event-python.o: defined in discarded
section
In Fedora, Python 3.7 added -flto to the list of --cflags and since it
was only applied to util/scripting-engines/trace-event-python.c and
scripts/python/Perf-Trace-Util/Context.c, linking failed.
It's not the first time the addition of flags has broken builds: commit
c6707fdef7 ("perf tools: Fix up build in hardnened environments")
appears to have fixed a similar problem. "python-config --includes"
provides the proper -I flags and doesn't introduce additional CFLAGS.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
