I don't think it's sufficient to do the check at build time, that makes
packing of plugins for distributions too complicated.
As it seems, people prefer that the plugin checks by itself whether the
right cpu is available and then run the correct processing loop. This
can be done within the init method every ladspa plugin has. And then
just select the right callback. That's probably the best solution then,
without changing anything in LADSPA.
