For the record, this worked for me:

( mkdir -p build.new ; cd build.new ; sh 
/w/jjg/work/tl/common/autoconf/configure --with-override-langtools=$(cd 
.. ; pwd) )

followed by

make -f build.new/Makefile  langtools


FWIW, it works well enough, but it does more than I need as a langtools 
developer. I just need what is now builld/langtools/classes in this new 
world; I don't need the *.{jar,zip} files to be created/updated, with 
the exception of the bootstrap javac.  And, because everything channels 
through the top level makefile, there appears to be no easy way to build 
interim targets in langtools/makefiles/Makefile, is that right?
