[PATCH] powerpc/Makefiles: Fix clang/llvm build

[Anton Blanchard]

From: Anton Blanchard <anton at samba.org>

Commit 15a3204d24a3 ("powerpc/64s: Set assembler machine type to POWER4")
passes -mpower4 to the assembler. We have more recent instructions in our
assembly files, but gas permits them. The clang/llvm integrated assembler
is more strict, and we get a build failure.

Fix this by calling the assembler with -mcpu=power8
