In my specific case, qemu-arm-static calls xargs (In fact, in my
cross chroot, qemu-arm-static is used to run every user mode process).

Do you mean that qemu-arm-static is exposing a latent defect in xargs?

Does qemu-arm-static steal some of the command line space that would
normally be available for xargs? If so, how would xargs figure out
this was happening and handle the problem?
