gcj-dbtool segfaults on hppa-linux-gnu and arm-linux-gnu; arm doesn't have
libjava support yet; the patches available from
http://gcc.gnu.org/ml/java/2006-08/msg00123.html were used.


rechecked both with a new 4.2 as a debian package and a vanilla 
upstream build. the installed gcj-dbtool crashes. I don't see the 
segfault, when gcj-dbtool is called during the build.
