Further tidy-up for old CPU architectures.

Browse Source 
Further to commit 92d70b77, let's drop the code we carry for the
following untested architectures: M68K, M88K, M32R, SuperH.  We have no
idea if anything actually works there, and surely as vintage hardware
and microcontrollers they would be underpowered for modern purposes.

We could always consider re-adding SuperH based on evidence of usage and
build farm support, if someone shows up to provide it.

While here, SPARC is usually written in all caps.
