Remove SPEC file from the source code

[stratakis]

Is there any reason to keep it in the sources? It's a maintenance burden with no real advantages from the upstream POV.

[hroncok]

My thoughts exactly. Drop it.

[stratakis]

It seems that the makefile uses it somehow though

[stratakis]

Not sure if there are any usecases for the recipes that use the SPEC

[stratakis]

Thinking if we should drop the Makefile as well.

[hroncok]

Yes.

[frenzymadness]

I think that we can drop both of them. I'm gonna do it.
