Hi All,

Reviews and sponsor requested for the removal of the now-redundant 
MAKE_SUBDIR argument in DeclareRecipesForPhase's comment, along with its 
removal from anything that calls that macro.

Bug: https://bugs.openjdk.java.net/browse/JDK-8253000

Webrev: http://cr.openjdk.java.net/~afarley/8253000/webrev/ 

Best Regards
