Log Message:
* Reimplement the wrapper script system so that it examines each argument
  and translates it into its buildlink equivalent, with caching to reduce
  the penalty of the translation.  This makes the wrappers robust against
  having quotes or spaces in the arguments, e.g. -DCPP=\"cc\ -E\".  A more
  complete description of the wrapper script system may be found in
  mk/buildlink2/README.

* Push the libtool fixes into a separate main wrapper script so that the
  archives are fixed as part of the creation of the libtool archive, and so
  from make(1)'s point of view, the libtool archive is created atomically.
  This prevents accidentally triggerring rebuilds of uninstalled libtool
  archives that depend on other uninstalled libtool archives during the
  installation process.

* Use a new variable name convention in the buildlink framework:

	_LT_* are private libtool-related variables
	LIBTOOL are publicly-usable libtool-related variables
	_BLNK_* are private buildlink-related variables
	BUILDLINK_* are publicly-usable buildlink-related variables
