Will 32-bit architecture be supported in the future?

[Wire-less-LAN]

Hi, I'm new to UCX. After some research I have decided to apply UCX to some embedded ARMv7 systems, only to encounter error while building:
/work/ucx/src/ucs/arch/cpu.h:111:4: error: #error "Unsupported architecture"
As listed in ucx/src/ucs/arch/cpu.h:111:4, it seems that only 64-bit arch are supported. Is it possible to use UCX on 32-bit arch? If not, is there any plan to support it in the future?
