Thanks. It looks like the first of the three options above is most 
similar to the verbosity
level of the old build. Is all of this documented anywhere?

I think at the very least, a cheat-sheet will be needed to help people 
transition between
the two systems, and options like the first one above will be very 
commonly used as part of that.
Maybe an actual flag value for that setting (as opposed to the empty 
string) might be more
meaningful.

Another minor (newbie) comment, is that some of the configure flags are 
documented (in --help)
as --with-XXX=PATH, but there are some that should be documented the 
same way, but aren't
(--with-boot-jdk is the one many will see first)
