Subject: mips: Include KBUILD_CPPFLAGS in CHECKFLAGS invocation
From: Nathan Chancellor <nathan@xxxxxxxxxx>
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.
