Since commit 5f73e7d0386d ("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.
Commit f354fc88a72a ("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.
