Hi Christof; .EXTRA_PREREQS is provided in 4.2.93 please test in your
environment.

Note that I did rework some things to allow it to work with implicit rules
(previously it only worked for explicit rules) although it still can't be
used as a pattern-specific variable: that will require more effort.  Also
some changes were made to make things a bit more efficient.
