Ok, thanks!

What I do is copying a working version from my openjdk installation to the expected location, so the build won't complain but actually I have no clue whats going on there. JamVM probably has the same problem, so I mostly hope for a good suggestion from your side, what should be done here.
I managed to work around this issue by creating a symbolic-link from libjsig.so to the jamvm libjvm.so
As can be seen in this changeset: http://icedtea.classpath.org/hg/icedtea7/rev/61e88e07618c
I will try do the same for cacao.

Sure, I will test it and send in a patch to update icedtea7.
