You can't.

  d> xsl/alldocs_%.xsl: genalldocs.php $(wildcard $(DOCS)/%/*.xml)

Functions and variables in target and prerequisite lists are expanded
when the makefile is read in.  That's when the $(wildcard ...) function
is expanded; the wildcard is seeing the literal "%" character here.

Pattern replacement doesn't happen until later when make is trying to
find an implicit rule to build the target.
