PATSUBST

   $(PATSUBST pattern...,to,text)

   Pattern substitution. Each word in 'text' that matches any
   'pattern'    word is replaced by 'to'. 'pattern' words may contain
   the wildcard characters * and %. If 'to' also contains wildcard
   characters, they will be replaced by the text that matched the
   wildcard characters in 'pattern'.
