This is the point behind the binary-delta solution - at runtime there will
only be one libstdc++ on the system and in use. The *only* thing we need
to control here is the contents of the DT_NEEDED header, the rest is
handled automatically. It took some time before we settled on this
solution but it is the only one that will work, as you observe.

I know what failures caused by mixed libstdc++ versions look
like, as I've debugged them before. We have already tested this
setup in build systems without libtool and it does work.
