Change the name of the _tryssl to an underbar prefix so we know it is
  an 'internal' thing, and try building explicit targets to avoid ever
  dragging in .bsc construction.

  Also introduce _browse.  This is far from complete, but I'm working on
  a mechansim to toggle browse database construction - of a single .bsc
  file for DevStudio's browser database.  The ugly bit is; it gobbles some
  80MB for construction, so we will never waste that sort of space on
  the typical case, but reserve it for developers who choose to toggle it.
