[PATCH] powerpc: allow cross-compilation of ppc64 kernel

When I try to cross compile a ppc64 kernel, it generally fails on the VDSO stage. This is true for powerpc64 cross- compiler, but also when I try to build a ppc64le kernel on a ppc64 host. VDSO64L fails: VDSO64L arch/powerpc/kernel/vdso64/vdso64.so.dbg /usr/bin/powerpc64-linux-gnu-ld:
