We don't know RVDS nor the .axf  file format - this seems to be
something really special, so I'm not surprised that these cannot be
executed in a standard Linux system.

Eventually your "vendor supplied kernel" has been modified to work
with RVDS, breaking compatibility with standard tool chains.

Please ask your vendor to provide support for RVDS or answer questions
about it - this is nothing where we can help you.
