The assembly portions of the MTE selftests need to be built with a toolchain supporting MTE. Since we support GCC versions that lack MTE support we have logic to suppress build of these tests when using such a toolchain but that logic is broken for LLVM=1 builds, it uses CC but CC is only set for LLVM builds in libs.mk which needs to be included after we have selected which test programs to build. Since all supported LLVM versions support MTE we can simply assume MTE support when LLVM is set. This is not a thing of beauty but it does the job.

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.
