Add support for $KERNEL_{CC,LD,LLVM} variables

Browse Source 
Currently, $(CC), $(LD), and $(LLVM) variables aren't passed to kbuild
while building modules.  This causes modules to build with the default
GNU GCC toolchain and prevents experimenting with other toolchains such
as CLANG/LLVM.  It can also lead to build failure if the CFLAGS/LDFLAGS
passed are incompatible with gcc/ld.

Pass $KERNEL_CC, $KERNEL_LD, and $KERNEL_LLVM as $(CC), $(LD), and
$(LLVM), respectively, to kbuild for each that is defined in the
environment.  This should take care of the majority of alternative
toolchain use cases.
