It looks like this is the same as using linux32, which I tried to no

It's probably worth that effort to build a zillion packages, but it 
seems like a nightmare of effort for building just one.  FWIW, every 
other part of the X stack just works with -m32 and the linux32 prefix. 
Mesa used to work.
