Alan Modra 1a72702bb3 Return void from linker callbacks 
The ldmain.c implementation of these linker callback functions always
return true, so any code handling a false return is dead.  What's
more, some of the bfd backends abort if ever a false return is seen,
and there seems to be some confusion in gdb's compile-object-load.c.
The return value was never meant to be "oh yes, a multiple_definition
error occurred", but rather "out of memory or other catastrophic
failure".

This patch removes the status return on the callbacks that always
return true.  I kept the return status for "notice" because that one
does happen to need to return "out of memory".

include/
	* bfdlink.h (struct bfd_link_callbacks): Update comments.
	Return void from multiple_definition, multiple_common,
	add_to_set, constructor, warning, undefined_symbol,
	reloc_overflow, reloc_dangerous and unattached_reloc.
