Regarding the illegal instruction, I don't think that it comes from
the icedtea patch. It sounds like the problem I had in
http://icedtea.classpath.org/bugzilla/show_bug.cgi?id=513.  It went
away when I built CACAO with -mfloat-abi=soft, not with
-mfloat-abi=softfp.

I verified that the current CACAO version works on both armv5 and
armv7. Unfortunately, I don't remember the exact build settings
anymore.
