You need *all* patches but the ABI patch. In the meantime, 2 more patches were 
added, as there where spurious reorderings.

For reproducible debug *source* packages, you also need a patched XSpp, as 
otherwise the generated sources include random IDs (these never end up in the 
binaries, the IDs are only used for #ifdefs used/removed by the C++ 
preprocessor).
