Unfortunately, I can't build libjava in the new tree (at least not without
hacking the generated Makefile):

It's picking up the wrong config.h, since the libstdc++-v3 include dirs have
pre-empted the libjava ones.

It looks like these libstdc++-v3 "-I" definitions are getting passed down
from the top-level configure in the $(CXX) variable?
