commit f62700ce63a315b4607cc9e97aa15ea409a677b9 upstream. selftests/bpf/Makefile includes tools/scripts/Makefile.include. With the following command make -j60 LLVM=1 LLVM_IAS=1 <=== compile kernel make -j60 -C tools/testing/selftests/bpf LLVM=1 LLVM_IAS=1 V=1 some files are still compiled with gcc. This patch fixed the case if CC/AR/LD/CXX/STRIP is allowed to be overridden, it will be written to clang/llvm-ar/..., instead of gcc binaries. The definition of CC_NO_CLANG is also relocated to the place after the above CC is defined.

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.
