There's a build failure for Book3E without AltiVec: Error: cc1: error: AltiVec not supported in this target make[6]: *** [/linux/scripts/Makefile.build:250: drivers/gpu/drm/amd/amdgpu/../display/dc/dml/display_mode_lib.o] Error 1 This happens because the amdgpu build is only gated by PPC_LONG_DOUBLE_128, but that symbol can be enabled even though AltiVec is disabled. The only user of PPC_LONG_DOUBLE_128 is amdgpu, so just add a dependency on AltiVec to that symbol to fix the build.
