Better than this, we can use Xcode's dependency system to not even run  
it unless the file has been updated since the last build. Just adds  
'touch the file' to the steps for adding a new libpurple build, and  
lets us avoid an always-runs non-parallel build step.

Further comments later, it sounds ambitious-but-possibly good so far.
