Since commit5f73e7d038("kbuild: refactor cross-compiling linux-headers package"), the linux-headers Debian package fails to build when $(CC) cannot build userspace applications, for example, when using toolchains installed by the 0day bot. The host programs in the linux-headers package should be rebuilt using the disto's cross-compiler, ${DEB_HOST_GNU_TYPE}-gcc instead of $(CC). Hence, the variable 'CC' must be expanded in this shell script instead of in the top-level Makefile. Commitf354fc88a7("kbuild: install-extmod-build: add missing quotation marks for CC variable") was not a correct fix because CC="ccache gcc" should be unrelated when rebuilding userspace tools.

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 reStructuredText 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.
