In my experience, this usually means that the dynamic linker can't be found
and nothing works. Look around for ld-linux.so.2 (or similar, depends on
architecture) in your runtime.

One thing that may be tripping you up is that a flatpak runtime requires
/usr merge. In particular, if your real dynamic linker lives in /lib, it
will be lost when creating the runtime because only /usr is committed.
