Please send your replies to the mailing list as well.

There were a few missing dependencies for the GTK2 build that I fixed
and bundled up in the v4 patch set. Additionally, I added a patch from
upstream to fix the ARM build. However, the v8 engine used to generate
the snapshot needs to use the same word size as the target
architecture, and that will take more toolchain work, so I've disabled
v8 snapshots for now.

Your config now builds successfully for me. Let me know your results.
