* ecoff.c: If compiling for DEC3100, use trad_unix core files,
else dummy out the core file support.
* trad-core.c (trad_unix_core_file_p): If HOST_DATA_START_ADDR is
specified, use it to locate the data section.
* coffcode.h (coff_write_symbols): Declare buffer as bfd_bytes
rather than as chars (lint).
