It's not impossible, but it does require some setup first. There's a
userspace-only version of qemu that translates target-machine system
calls into native system calls, and you can set up Linux's support for
custom binary formats so qemu-user gets invoked automatically when you
try to run a non-native executable. The emulation's not as good as
qemu's full-machine emulation (in particular, it tends to have limited
support for recently-added system calls), but it usually works well
enough for bootstrapping.

The Debian wiki has some notes on how to set it up:
