Commit3fb0fdb3bb("x86/stackprotector/32: Make the canary into a regular percpu variable") modified the stackprotector check on 32-bit x86 to check if gcc supports using %fs as canary. Adjust dummy-tools gcc script to pass this new test by returning "%fs" rather than "%gs" if it detects -mstack-protector-guard-reg=fs on command line.

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.
