commit8ce72dc325("selftests: fix headers_install circular dependency") broke bpf build/test workflow. When KBUILD_OUTPUT is set, bpf objects end up in KBUILD_OUTPUT build directory instead of in ../selftests/bpf. The following bpf workflow breaks when it can't find the test_verifier: cd tools/testing/selftests/bpf; make; ./test_verifier; Fix it to set OUTPUT only when it is undefined in lib.mk. It didn't need to be set in the first place.

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.
