Android has an unusual setup where the kernel needs to target [arch]-linux-gnu to avoid Android userspace-specific flags and optimizations, but AOSP doesn't ship a matching binutils. Add a new variable CLANG_TRIPLE which can override the "-target" triple used to compile the kernel, while using a different CROSS_COMPILE to pick the binutils/gcc installation. For Android you'd do something like: export CLANG_TRIPLE=aarch64-linux-gnu- export CROSS_COMPILE=aarch64-linux-android- If you don't need something like this, leave CLANG_TRIPLE unset and it will default to CROSS_COMPILE.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
