buildtools: detect discrepancies for experimental symbols

Browse Source 
When promoting those symbols as stable, there is no check to ensure that
the final result is consistent.

Add a little script to get the symbols per section from the library map
files.
Validate that all experimental symbols in object files are referenced by
library map files.
