- a flag that indicates that we have previously done an initial symbol

- absence of any of the three symbol tables (msymbols, psymtab, symtab)
- because if the file has no symbols for example, none of these will

shared libraries exhibit this behaviour), we will need an expensive
algorithm to locate a partial symtab or symtab via an address.
To avoid this penalty for normal object files, we use this flag,
whose setting is determined upon symbol table read in. */
