The HAVE_ext should probably be outside the function. The compiler
should eliminate the assignment of a symbol in the init function if
HAVE_ext is zero (that's called dead code elimination), so that the
function is then unused anyway.

Otherwise looks good, except for that weird start at the top of the
SSSE3 function but I guess I don't quite know how to fix that.
