        The target in the PR says powerpc64-linux, which is what confused
Andrew and me.

        There is a valid mode of Altivec programming using builtins and
asms that does not require the Altivec ABI.  That is what -maltivec
supports.

        I suspect that -ftree-vectorize should enable -mabi=altivec by
default on PowerPC.
