I wasn't able to reproduce this problem on v1 but found a similar issue on v2. I just did a build test of each patch of the latest version (v3) with an s390 cross-toolchain and the config file from this report and didn't find any build issues, so I believe this problem is solved. -- Thiago Jung Bauermann IBM Linux Technology Center
