From a7e5eb53bf9b800d086e2ebcfebd9a3bb16bd1b0 Mon Sep 17 00:00:00 2001 From: Nathan Chancellor Date: Thu, 1 Jun 2023 11:46:33 -0700 Subject: [PATCH] powerpc/vdso: Include CLANG_FLAGS explicitly in ldflags-y 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 the compat PowerPC vDSO: clang: error: unsupported option '-mbig-endian' for target 'x86_64-pc-linux-gnu' make[3]: *** [.../arch/powerpc/kernel/vdso/Makefile:76: arch/powerpc/kernel/vdso/vdso32.so.dbg] Error 1 Explicitly add CLANG_FLAGS to ldflags-y, so that '--target' will always be present.
