This error means that the program interpreter is missing. Bash gives a much better error message than ash does. You can see the same error if you create a shell script like this

#!/bin/nonexistant
exit 0

and try to run it.

For a binary, the program interpreter is the dynamic linker. If you go back to your host system, and run "riscv64-unknown-linux-objdump --full-contents --section .interp test" it will print the name of the dynamic linker. This file is missing on your target system. This problem usually occurs when your cross compiler and your target system are using different glibc versions. The glibc versions must match if you want dynamic libraries to work. Or maybe the glibc on your target was built without shared library support.

The simple workaround is to static link binaries. Add the --static option to the gcc command to get a statically linked binary, which then should run on your target.
