In principle, it should be possible to compile Octave for 32-bit hosts (bare 
metal or emulated). (We are still doing that for 32-bit Windows with MXE 
Octave.)
You'd need to have access to a (cross-)compiler that supports C++11 (GCC 4.8 or 
newer?).
You'd also need all dependencies for the same host platform.
General build instructions are on the Wiki:
