The next cset needs to compare if a flex version is greater or equal/less than another, but since there is no canonical, generally available way to compare versions in the command line (sort -V, yeah, but...), just use awk to canonicalize the versions like is also done in scripts/rust_is_available.sh. There was a problem spotted in linux-next where a bashism, here documents, aka the '<<<' stdin redirector, for strings to be used as the stdin for awk. Use $(shell echo | awk ...) instead.

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.
