powerpc/64s: Set assembler machine type to POWER4
Rather than override the machine type in .S code (which can hide wrong or ambiguous code generation for the target), set the type to power4 for all assembly. This also means we need to be careful not to build power4-only code when we're not building for Book3S, such as the "power7" versions of copyuser/page/memcpy. Signed-off-by: Nicholas Piggin <npiggin@gmail.com> [mpe: Fix Book3E build, don't build the "power7" variants for non-Book3S] Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
