The stackprotector support in nolibc should be enabled iff it is also enabled in the compiler. Use the preprocessor defines added by gcc and clang if stackprotector support is enable to automatically do so in nolibc. This completely removes the need for any user-visible API. To avoid inlining the lengthy preprocessor check into every user introduce a new header compiler.h that abstracts the logic away. As the define NOLIBC_STACKPROTECTOR is now not user-relevant anymore prefix it with an underscore.

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.
