difference would be installation/deployment. The idea would be that instead of
the 32-bit and 64-bit runtimes being installed directly in parallel on the base
system, they would instead be installed into effectively a chroot with its own
completely 32-bit runtime.
Downstream doesn't provide these chroots for the 32-bit variants at
present, so I expect that most 32-bit build environments use the -m32
(or -m31) approach there. This is a very significant change. (Of
course, an even more significant change is just around the corner:
32-bit architectures are almost out of the picture anyway.)
Or you end up cross-compiling, with some path/sysroot hackery. Even if
the kernel could theoretically run the built binaries, all the userspace
libraries are still missing, so it would effectively be cross-compilation.
