The jevents command expects all json files to be organized under a single directory. When generating json files from scripts (to reduce laborious copy and paste in the json) we don't want to generate the json into the source directory if there is an OUTPUT directory specified. This change adds a GEN_JSON for this case where the GEN_JSON copies the JSON files to OUTPUT, only when OUTPUT is specified. The Makefile.perf clean code is updated to clean up this directory when present. This patch is part of: https://lore.kernel.org/lkml/20240926173554.404411-12-irogers@google.com/ which was similarly adding support for generating json in scripts for the consumption of jevents.py.

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.
