Ryan,

The content of Conf/build_rule.txt is used to construct the makefiles. The rules under <Command.GCC> will get translated into the generated makefiles. If you prepend an @ that makefile line should no longer echo. 

The Conf/build_rule.txt will get copied from the BaseTools/Conf//build_rule.template if it does not exist when you run edksetup.sh. 

You can always add an @print line to print out anything you want. 

Thanks,

Andrew Fish
