makefile changes: make stops on error immediately

["Mark M. Ito" <marki@jlab.org>]

I have checked in some changes to some of the high-level makefiles so 
that when a series of directories are built, make will terminate as soon 
as an error is detected in any one of the directories. I think this is 
the behavior we want; let me know if you disagree.

I may not have gotten them all. Let me know if you find some that need 
the change (assuming you agree with it).
