Compiler plugins don't work with profiling

Suppose I have a normally built compiler plugin, and I'd like to use it while building some profiled code. This doesn't work: (non-profiled) GHC searches for the profiled version of the plugin. This is wrong wrong wrong: plugin searches should be with respect to how GHC was compiled. (Test case: take the plugins01 test and add -prof to it)

Now that we have -plugin-package, it should be a simple matter to ensure that plugin lookups follow a different codepath, though I'm not sure how to figure out what GHC is built with; this should just be however TH does it.
