     # We have several cases where archives depend on each other in a cyclic
     # fashion. (V8Bindings, libport and WebCore being the most significant
     # example.) Since the GNU linker does only a single pass over the archives
     # we need some extra trickery to deal with these unavoidable cycles. That
     # trickery is --start-group and --end-group (aka -( and -) ). That causes ld
     # to loop over the group until no more undefined symbols are found. In an
     # ideal world we would only make groups from those libraries which we knew
     # to be in cycles. However, that's tough with SCons, so we bodge it by
     # making all the archives a group by redefining the linking command here.
