I have thoroughly reviewed all the build changes, and they look good to 
me, with the following remarks.

It would have been nice to use the new "wrapper" based approach for all 
module-phase specific details -- this is done now for all phases except 
gensrc and rmic. But this is not necessary for the patch to work, and 
can be addressed later on.

We also need to update configure to accept a module-based JDK as a boot 
JDK. In the patch, this is done sort-of -- we can run a bootcycle build 
with the new module-based JDK, but we will not accept it as an initial 
boot JDK. But this too can be fixed later on.

And of course there is always some syntax issues. :-) In 
langtools/make/gensrc/Gensrc-jdk.*.gmk, there are several calls of the 
pattern:
$(eval $(call SetupVersionProperties,JAVAP_VERSION, ...))
$(eval $(call SetupCompileProperties,COMPILE_PROPERTIES, ...))
These should have a space following the comma to adhere to the 
recommended style. But once again, I'm okay with fixing this in a follow up.
