[7u6] Please review my fix for 7172430: [macosx] debug message in non debug jdk build

[Alexander Zuev]

Hello,

   please review my fix for CR 7172430: [macosx] debug message in non 
debug jdk build
   CR description can be found here: 
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7172430

   Webrev with the proposed change can be seen here: 
http://cr.openjdk.java.net/~kizune/7172430/webrev.00

   The fix is quite simple - i have no idea why this code was not 
safeguarded by corresponding #if/#endif in the first place, but well..

With best regards,
Alex
