RFR: JDK-8057537: Serialize reconfigure and fix make clean-foo foo

[Erik Joelsson]

Hello David,

I hear your pain and when reading this got to thinking that separating 
clean and reconfigure targets shouldn't be that hard. I came up with 
this solution:

Bug: https://bugs.openjdk.java.net/browse/JDK-8057537
Webrev: http://cr.openjdk.java.net/~erikj/8057537/webrev.root.01/

It separates the clean and reconfigure targets from the rest in the root 
Makefile and runs them separately with -j1. This also solves the problem 
of those targets not working well with the timer and summaries.
