Let's give this another go. I've included a patch against master this time.
For a reminder, the problem is that libltdl mangles library names for the preload table, but libtool does not, resulting it being impossible to look up things. Also, some programs expect the library names in the preload table to be unmangled so we need to change libltdl to stop doing that.

Subject: [PATCH] Make libltdl stop mangling preloaded names.
Store the original name for lookup in the preload table as that is what
libtool puts in there, not the mangled version libltdl was previously
using.
