Running "unbuffer qemu-aarch64 $program > $file" allows to pipe the
output.
Is it intentional that I need to disable buffering to allow piping to
other processes? If yes, this issue can be closed.

No, this should work on qemu-aarch64 the same way as for x86. I just
tried redirection to a file with a sample program, and it worked fine
for me. Can you provide a test case binary that fails like this, please?

This issue is now marked as invalid, sorry for the trouble.
qemu works just fine. The problem was with my linker configuration, it
was using a different dynamic library for aarch64. Switching to a
standard development stack solved my problem.
