Older versions of BSD awk are fussy about the order of '-v' and '-f' flags, and require a space after the flag name. This causes build failures on platforms with an old awk, such as macOS and NetBSD. Since GNU awk and modern versions of BSD awk (distributed with FreeBSD/OpenBSD) are fine with either form, the definition of 'cmd_unroll' can be trivially tweaked to let the lib/raid6 Makefile work with both old and new awk flag dialects.

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.
