I'm no cross-compilation expert. At best I can refer you to:

  https://backports.wiki.kernel.org/index.php/Documentation/packaging

The "cannot execute binary file" can mean:
 - invalid libc linking
 - missing +x permissions on file (unlikely)
 - missing +x permissions on filesystem (e.g. due to "noexec" mount option)
 - trying to run a binary destined to a different arch

You'll have to figure it out yourself.

As an alternative you might want to use QEMU and do emulated native
compilation (e.g. Debian with deboostrap) but I will not go into
detail how to do this as it's not trivial.
