Hi, not sure I understand your question. If you build a cross compiler targetting a 32bit device (say Raspbian/Raspberry Pi) for say x86_64 linux, you end up with a 64bit compiler emitting code for a 32bit device.
If you question revolves around dynamically changing GHCs target at runtime. Essentially turning GHC into a multi-target compiler, we hope to get there eventually. Please not that just emitting a single module in 32bit is likely not going to get you far. You will still need to build the rts and potentially some additional support libraries to turn that module into something useful.
