You can either continue to use GNU make 3.81, or change your makefiles
(you have to split the rule into two rules, one that is explicit and one
that's a pattern rule).  The "new way" works with all versions of GNU
make.  See this from the NEWS file for GNU make 3.82:

* WARNING: Backward-incompatibility!
  In previous versions of make it was acceptable to list one or more explicit
  targets followed by one or more pattern targets in the same rule and it
  worked "as expected".  However, this was not documented as acceptable and if
  you listed any explicit targets AFTER the pattern targets, the entire rule
  would be mis-parsed.  This release removes this ability completely: make
  will generate an error message if you mix explicit and pattern targets in
  the same rule.
