arm64: vdso32: suppress error message for 'make mrproper'
commit 14831fad73f5ac30ac61760487d95a538e6ab3cb upstream. When running the following command without arm-linux-gnueabi-gcc in one's $PATH, the following warning is observed: $ ARCH=arm64 CROSS_COMPILE_COMPAT=arm-linux-gnueabi- make -j72 LLVM=1 mrproper make[1]: arm-linux-gnueabi-gcc: No such file or directory This is because KCONFIG is not run for mrproper, so CONFIG_CC_IS_CLANG is not set, and we end up eagerly evaluating various variables that try to invoke CC_COMPAT. This is a similar problem to what was observed in commit dc960bfeedb0 ("h8300: suppress error messages for 'make clean'") Reported-by: Lucas Henneman <henneman@google.com> Suggested-by: Masahiro Yamada <masahiroy@kernel.org> Signed-off-by: Nick Desaulniers <ndesaulniers@google.com> Reviewed-by: Vincenzo Frascino <vincenzo.frascino@arm.com> Reviewed-by: Nathan Chancellor <nathan@kernel.org> Tested-by: Nathan Chancellor <nathan@kernel.org> Link: https://lore.kernel.org/r/20211019223646.1146945-4-ndesaulniers@google.com Signed-off-by: Will Deacon <will@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
