5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nathan Chancellor nathan@kernel.org
commit 08f6554ff90ef189e6b8f0303e57005bddfdd6a7 upstream.
A future change will move CLANG_FLAGS from KBUILD_{A,C}FLAGS to KBUILD_CPPFLAGS so that '--target' is available while preprocessing. When that occurs, the following error appears when building ARCH=mips with clang (tip of tree error shown):
clang: error: unsupported option '-mabi=' for target 'x86_64-pc-linux-gnu'
Add KBUILD_CPPFLAGS in the CHECKFLAGS invocation to keep everything working after the move.
