changed calling convention for Q_enter_global_ref

Browse Source 
* 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.

/* ldindr.c
Handle indirect symbols.
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,
