Support building zero with the new build

[Erik Joelsson]

Work on this was already initiated in this thread:

http://mail.openjdk.java.net/pipermail/build-infra-dev/2013-February/003059.html

Would be good if these efforts could be synchronized.

I like that you define and translate these hotspot specific variables in 
hotspot-spec.gmk. I don't think we need to change any variables in 
hotspot for this to work as was done in the other thread. ZERO_ARCHDEF 
should maybe belong to platform.m4, not sure, but might as well be 
defined where you have it. However, checking for libraries would be 
better moved to libraries.m4 I think.
