 6.11 Pattern-specific Variable Values
 =====================================
 
 In addition to target-specific variable values ( Target-specific
 Variable Values Target-specific.), GNU `make' supports
 pattern-specific variable values.  In this form, the variable is
 defined for any target that matches the pattern specified.  If a target
 matches more than one pattern, all the matching pattern-specific
 variables are interpreted in the order in which they were defined in
 the makefile, and collected together into one set.  Variables defined
 in this way are searched after any target-specific variables defined
 explicitly for that target, and before target-specific variables
 defined for the parent target.
 
    Set a pattern-specific variable value like this:
 
      PATTERN ... : VARIABLE-ASSIGNMENT
 
 or like this:
 
      PATTERN ... : override VARIABLE-ASSIGNMENT
 
 where PATTERN is a %-pattern.  As with target-specific variable values,
 multiple PATTERN values create a pattern-specific variable value for
 each pattern individually.  The VARIABLE-ASSIGNMENT can be any valid
 form of assignment.  Any command-line variable setting will take
 precedence, unless `override' is specified.
 
    For example:
 
      %.o : CFLAGS = -O
 
 will assign `CFLAGS' the value of `-O' for all targets matching the
 pattern `%.o'.
