If you're going to be insulting when offered advice, please don't
expect to get help again.

I recommended using objcopy because objcopy supports modifying symbol
tables and GDB does not.  You can write a GDB macro to use objcopy to
add the symbol, replace the original binary, and reload it into GDB.
It'll be about five lines.  This will be about a million times easier
than trying to add a new GDB command to modify the symbol table.
