Need reviewer: old echo -e issue and some sanity check cleanup

[Kelly O'Hair]

Need reviewer, had this change sitting around and forgot about it.

6535379: Restructure echo messages in makefiles, avoid echo -e

http://cr.openjdk.java.net/~ohair/openjdk7/sanitycleanup/webrev/

Creates some common patterns for sanity errors into make macros, and  
changes from
"echo" to "printf" to avoid the dependence on 'echo -e'.

Let me know what you think.
