It does work in the sense that it always fails. I proposed a long time
ago that we should support it in a limited form to be able to rip out a
lot of complexity from NSS and PAM code: you can compile a list of
modules in and have those register exported symbols for use with dlsym,
but that's it. I certainly don't want to do the kind of dynamic linking
emulation that glibc has in its static libc.
