It's an interesting thing but the file has decreased by 7472 bytes with
-Og and by 6896 bytes with -O3 optimization level (debug info enabled).
Despite that readelf(1) sees a new local symbol, _dl_resolve_map.

When debug info is disabled with the -g0 flag, size of the file is also
reduced by 3296 and 1440 bytes respectively.
