SPARC is no longer being used in any multimedia-related fields and the
VIS optimizations only represent a maintenance burden.

SH4 has been end-of-lifed and no more test machines are available.

Previously, it was an implicit dependency through mpegvideo. Change
this, as implicit dependencies can cause all sorts of trouble.
