While I understand what you're trying to do, I'm not sure it's a
reasonable goal for Buildroot to be able to provide binary
compatibility between systems generated by different Buildroot
versions. We regularly update libraries to their latest upstream
versions, and sometimes they break the ABI compatibility. I don't think
we want to enter the game of ensuring that ABI compatibility is ensured
between Buildroot versions.
If you're building a program with a given Buildroot SDK, it should be
executed on the Buildroot system that matches that SDK.
Best regards,
Thomas
