commit 5ddc7a3794ddd3470635ebd325fa1dffea5b18c0 upstream.
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.
