Below excerpt from GNU make manual - subsection "Target-specific 
Variable Values".

   The other exception is "target-specific variable values".  This
feature allows you to define different values for the same variable,
based on the target that `make' is currently building.  As with
automatic variables, these values are only available within the context
of a target's command script (and in other target-specific assignments).
   Set a target-specific variable value like this:
     TARGET ... : VARIABLE-ASSIGNMENT
or like this:
     TARGET ... : override VARIABLE-ASSIGNMENT
