Yes, assuming all 32-bit libraries are present and you have gcc multilib
installed, you can configure with "-m32" added to CFLAGS, CXXFLAGS,
FFLAGS.

I think that's a non-starter on Debian because a lot of the math/sci
libraries are not yet multiarched, so it's harder to install a 32-bit
blas, etc.

I've used both docker and vagrant to set up containers or VMs to build
Octave for other distros. I like these approaches because they are
command line driven and they allow me to easily share my Octave build
directory with the guest OS. I can write up something on how to set up
either if needed.
