Subject: LoongArch: Include KBUILD_CPPFLAGS in CHECKFLAGS invocation
From: WANG Xuerui <git@xxxxxxxxxx>
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.
