SPARC: why it's not registerised anymore?

[Christian Maeder]

Hi Karel,

the last version of a registered build (that I know about and worked for 
me) is ghc-7.0.4 (see below). I was not able (or gave up) to build 
ghc-7.2 on sparc.

https://ghc.haskell.org/trac/ghc/ticket/7106#comment:3 for ghc-7.4
says that "Sparc is unregisterised now that the registerised C backend 
has been removed".

Cheers Christian
