Deprecation warning to assist with migration to new binary names (#8283)

Browse source 
* Adding a simple program to provide a deprecation warning that can exist to help people notice the binary name change from #7809 and migrate to the new filenames.

* Build legacy replacement binaries only if they already exist. Check for their existence every time so that they are not ignored.
