changed calling convention for Q_enter_global_ref

* ldexp.c, ldlang.c, ldmain.c: reflect this
	* ldver.c: bump version to 1.97.1
	* ldindr.c (add_indirect): when an edict declaring an indirect
	symbol is found, make sure that any ideas about the symbol being
	common are changed if it now known to be defined.
	* ldmain.c (linear_library): complain once if archive isn't
	ranlibbed.
	* ldlang.h, ldlang.c: make room for and initialize the complain
	once field.

+   An indirect symbol is where a global symbol in one file say's that
+   all refs like it should be turned into refs of the symbol pointed
+   at by the value of the indirect symbol.

    BFD supplies symbols to be indirected with the BFD_INDIRECT bit
    set. Whenever the linker gets one of these, it calls add_indirect
    with the symbol. We look up the symbol which this one dereferneces,
