s390 does not support the "global" stack protector mode that is implemented in nolibc. Now that nolibc detects if stack protectors are enabled at runtime it could happen that a future compiler does indeed use global mode on and nolibc would compile but segfault at runtime. To avoid this hypothetic case and to align s390 with the other architectures disable stack protectors when compiling _start().

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.
