Thanks, I got it to work now. (The problem? I was defining MEMDEBUG2, and this does not seem to work for 32 bits. I filed an issue here: https://github.com/JuliaLang/julia/issues/10942)

On a proper multi-arch system, I believe those binaries should be content to live side-by-side (that's how my Ubuntu system is configured anyhow). Failing that, perhaps look into creating a linux container or chroot?

    Thank you, that is a very good point.  Let me be a bit more
    specific then.

    Has anybody had success building both 32-bit Julia and 64-bit
    Julia on a
    single (multiarch 64-bit) Linux installation?  Looking at 32-bit
    .travis.yml, it replaces many packages (e.g. binutils, gcc) with their
    i386 versions.  I would instead like to build a 32-bit Julia without
    hosing my machine in that way.
