* libcoff-in.h (struct coff_final_link_info): Add boolean

Browse Source 
global_to_static member for support of task linking.
	(_bfd_coff_write_task_globals): Add prototype.
	* libcoff.h: Regenerate.
	* coffcode.h (coff_write_object_contents): Use #ifdef to
	check RS6000COFF_C, to be consistent with all other uses
	in this file.
	* cofflink.c (_bfd_coff_final_link): If doing task linking,
	call _bfd_coff_write_task_globals.
	(_bfd_coff_link_input_bfd): If doing task linking, convert
	global functions to static.
	(_bfd_coff_write_global_sym): If doing task linking, convert
	global variables to static.
	(_bfd_coff_write_task_globals): New function.
	* coff-tic80.c (TIC80COFF): Define this instead of just TIC80.
	(C_AUTOARG): #undef since it clashes with C_UEXT.
	(C_LASTENT): #undef since it clashes with C_STATLAB.
	* coffcode.h (coff_write_object_contents): Use TIC80COFF
	rather than TIC80.
	(coff_slurp_symbol_table): Use C_SYSTEM.  Hide C_AUTOARG use
	when TIC80COFF defined (clashes with C_UEXT).  Explicitly
	recognize C_UEXT, C_STATLAB, and C_EXTLAB as unsupported.
