New build = old build on all platforms

[Erik Joelsson]

Today marks a big milestone in the build-infra project as we can now 
declare that the new build is able to produce equivalent j2sdk and j2re 
images compared to the old build for all openjdk platforms.

The platforms are:
linux-x86, linux-x86_64,
windows-x86, windows-x86_64,
solaris-x86, solaris-x86_64, solaris-sparc, solaris-sparcv9
macosx-x86_64

Equivalent does not mean bit by bit equal. There will be some 
unavoidable differences and the extent of these vary depending on 
platform. Our definition of equality is encoded into the compare script. 
More information about how the script works and how to use it can be 
found here:

Does this mean we are done?
No, there are a number of issues still to handle. Stability, ergonomics 
and missing features from the old system, to name a few.
