The total size of all sections may be larger than the total size of
all symbols.  There are structures in your application, like the
symbol table, which do not have an associated symbol.

If you just want the memory requirements of your application, I
recommend using m68k-elf-size or m68k-elf-readelf -l (lowercase
L).
