dolphin/: Need a 64-bit compile which is feasible however there would be no graphics as graphics libs provided by LG are 32-bit only.
You're building on an unsupported platform: 'armv7l' with 4-byte pointers.
Enable generic build if you really want a JIT-less binary.
dolphin_launcher: (removed as pointless without dolphin)
