make: .NOTPARALLEL and .WAIT are special targets

Austin Group defect report 1437 has been accepted.  It describes
the special targets .NOTPARALLEL and .WAIT which are used to
influence the behaviour of parallel builds.

Since parallel builds aren't implemented in here they actually don't
't have much effect.

- For completeness they're flagged as special targets.

- .WAIT should be allowed as a prerequisite.
