  The DB_*_SYMBOLS is needed so that ddb knows what kind of symbol table
is present.  [I'm assuming that the ELF symbol table format is different -
I haven't checked this yet.]  I think that the comment may have come from
when the DB_ELF_SYMBOLS was originally added to the file, but since the
pmax was currently using aout kernels, the DB_AOUT_SYMBOLS was defined,
but the comment didn't get updated.
