Enable the base GCC plugin support symbol CONFIG_GCC_PLUGINS for multi_v7_defconfig so that builds hosted on systems that have a supported version of GCC along with the prerequisite headers will allow GCC plugins to be used during the build. At the moment, this will also enable the ARM per-task stack protector plugin, since all its remaining Kconfig dependencies are fulfilled by default. At the same time, enable the structleak plugin. This plugin ensures that local struct type variables are fully initialized, preventing inadvertent leaks of kernel state if such variables are shared with userland. This is a reasonable transformation to apply by default, since it does not adversely affect performance, and does not affect GCC compiler diagnostics regarding the use of uninitialized local variables.

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.
