For the preopen, dlopen, shl_load loaders, I confirmed that the
testsuite addition exposes the bug, and the loader changes fixes the
testsuite failure.  For loadlibrary, I only cross-compiled from
GNU/Linux to ensure absense of typos.

I visually inspected the BeOS and dld changes again for typos, and then
applied the patch, after adding a NEWS entry.

My pleasure.  :-)  Kudos to Andreas for reporting the bug.
