liquid-dsp: fix powerpc/altivec build failures

Browse Source 
When a powerpc target is detected the build system tries to force
altivec support but that's wrong:

Not every powerpc processor has altivec instruction support.

It's using the removed/deprecated -faltivec compiler directive when it
should be using -maltivec instead.

Even if the above conditions are corrected the altivec codepath fails
to build properly.

So just disable altivec in general using the standard
--enable-simdoverride configure option. Fixes:
