It's a new architecture.
We don't require people to use --disable-asm on Sparc, MIPS or ARM, all of which have little to no asm code. And all of those are at least as relevant as x32, ARM and MIPS are in fact vastly more significant.
Mainly I do not like it though since it means every distribution needs to add a special case in the build instructions.
