LoongArch: Include KBUILD_CPPFLAGS in CHECKFLAGS invocation
This is a port of commit 08f6554ff90e ("mips: Include KBUILD_CPPFLAGS in
CHECKFLAGS invocation") to arch/loongarch, for fixing cross-compilation
of Linux/LoongArch with Clang, where previously the `--target` flag
would no longer be present for the CHECKFLAGS cc invocation leading to
build failure.
