powerpc/vdso: No need to undef powerpc for 64-bit build
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.
