The joke here is: I'm not using vector arguments, nor varargs, I don't
need vectors on the stack and nothing. In theory I should be able to
live without -mabi=altivec if there wasn't this nasty segfault at -O0.

That would be me! I know what I'm doing, have no intention to pass
vector arguments or use varargs.
