[ I get errors "invalid opcode stvx, mtvrsave, mfvrsave etc". ]

I suspect vg_ppc_helpers.S needs to somehow not use altivec if not present.
Maybe you could surround the innards of the load_vec_state etc. functions with #if HAVE_ALTIVEC,
and add a check for altivec assembler support into the configure script ?
Good luck!
