The libunwind java bindings try to build on architectures where libunwind is not currently supported. This causes the build to break on PPC/PPC64 systems. Unpleasant things must be done to fix the build right now. The java bindings should use the same variable used when the libunwind library is removed from the build system.
Now that ppc64 stubs for libunwind are already in Frysk, this should not be a big problem right now. Lowering its priority.
Cannot dup in current version.
