Why not? As far as I can tell from the gcc configury, the target string only affects the defaults (i.e. powerpc-*-linux gets -mno-spe -mno-altivec, powerpc-*-linuxaltivec gets -maltivec -mno-spec, and powerpc-*-linuxspe gets -mno-altivec -mspe). There doesn't seem to be any real impact beyond this that would make the compiler binary fundamentally incapable of generating either type of instruction if you pass the appropriate options on the command line. p.
