tcg: Remove unsupported backends

Browse source 
I really don't want to support all these backends on an ARM-focused
backend.

Also the notion of someone saying
"yes, I would like to compute things using MIPS/SPARC/PPC instead of
literally anything else" is wild to me.

Thus, I will solve the problem by simply not thinking about it
whatsoever.
