The vdso Makefile adds -U$(ARCH) to CPPFLAGS for the vdso64.lds linker script. ARCH is always powerpc, so it becomes -Upowerpc, which means undefine the "powerpc" symbol. But the 64-bit compiler doesn't define powerpc in the first place, compare: $ gcc-5.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc -m32 -E -dM - </dev/null | grep -w powerpc #define powerpc 1 $ gcc-5.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc -m64 -E -dM - </dev/null | grep -w powerpc $ So there's no need to undefine it for the 64-bit linker script.
