[gdb/symtab] Recognize .gdb_index symbol table with empty entries as empty
When reading a .gdb_index that contains a non-empty symbol table with only
empty entries, gdb doesn't recognize it as empty.
Fix this by recognizing that the constant pool is empty, and then setting
the
symbol table to empty.
Tested on x86_64-linux.
