If you already have a bootstrapped icedtea or openjdk on the system then
it isn't strictly necessary and you can also configure --with-icedtea or
--with-openjdk and it will use that for the bootstrapping phase. See
also ./configure --help for some more options to specify the "home dir"
for these installations if you got them in a non-default place.

I CCed the icedtea list (distro-pkg-dev), but that (luckily) also
doesn't do the harmful reply-to header munging (but that is probably
another bikeshed flamewar waiting to happen...).
