OK, that's because libtool reoders the arguments list, so that all libraries
( args staring with -l ) comes after all library paths ( args starting with
-L ). And it does so by moving all non -l arguments to the beginning of the
list, and all -l arguments at the end of the list.

Unfortunately, -Wl,-Bstatic,-lstdc++,-Bdynamic does not start with -l, so
it is moved before all -l args, and thus libstdc++ is scanned before any of
its members is needed, so it does not get linked.

Sigh.

Passing LDFLAGS=-lstdc++ seems to be enough, though.

Done. We might be able to get rid of the wrapper very shortly, I hope.
