sim: ppc: drop useless linking of helper tools

We've never run these helper programs directly.  The igen program
includes the relevant source files directly and runs the code that
way.  So stop wasting developer CPU time linking programs that are
never run.  We leave the rules in place for people who need to test
and debug the specific bits of code every now & then.
