Why does solib_open do what it does?

Okay gentlemen, all kidding aside, what do we do?  At the bare minimum I
believe the test

  /* If not found, next search the inferior's $PATH environment variable. */
  if (found_file < 0 && solib_search_path != NULL)

should be just:

if (found_file < 0).

We can always make a decision about removing the PATH and LD_LIBRARY_PATH
checks later.

cheers,
