I think x86 and ARM are a bit confusing in this regard, as they can refer to 32-bit architectures in a narrow sense and 32-bit or 64 bit architectures in a broad sense.

For clarity, we can use more specific names: `x86-32`/`i686` and `arm32`/`aarch32`. But these names don't seem to be that commonly used.
