* Preliminary support for m88k-coff.
* configure.in (m88k-*-coff*): New target. Use coffbfd and
m88kcoff.
* config/m88kcoff.mt: New file.
* read.c (lex_type): New macro LEX_AT to set lex type of '@'.
(pseudo_set): Handle difference of symbols in different fragments
by saving the entire expression as the value of the symbol.
* symbols.c (resolve_symbol_value): Resolve difference
expressions.
* config/obj-coffbfd.c (obj_pseudo_table): If TC_M88K, accept
"sdef" as a synonym for "def".
* config/obj-coffbfd.h: If TC_M88K, include coff/m88k.h and set
TARGET_FORMAT.
(S_IS_LOCAL): Any symbol which includes \001 in the name is local.
* config/tc-m88k.c, config/tc-m88k.h: Numerous changes to bring
m88k port up to date, and to add COFF support.
