OK, but that just breaks pre-opening completely, doesn't it?

What's the underlying issue here?  Has libtool 2 dropped support for
pre-opening, or is there a different incantation needed for loading
pre-opened symbols, or is there something about Guile's build that
prevents libltdl from exporting lt__PROGRAM__LTX_preloaded_symbols?

Perhaps the point is that when libltdl was built, it knew it was for a
platform that supported proper dlopen, and hence that pre-opening
support should never be needed?  In that case, is there a
configure-time test we can do to discover whether the available
libltdl has pre-opening support or not?

Thanks,
