[gentoo-dev] [PATCH] kernel-2.eclass: Respect portage CC variable

[Adrian Ratiu <adrian.ratiu@collabora.com>]

Starting with kernel >= v5.7 the build system can override this
variable by passing LLVM=1 [1], but for older kernels or in
cases where the LLVM toolchain is setup directly via portage,
CC should be respected to avoid situations like building the
kernel with clang but the headers with gcc.

[1] a0d1c951ef08 kbuild: support LLVM=1 to switch the default tools to Clang/LLVM
