The diagnostics for this case are already decent. Here's an example:
$ /prefix/bin/who
/prefix/bin/who: error while loading shared libraries: libsystemd.so.0: cannot
open shared object file: No such file or directory
$ LD_TRACE_LOADED_OBJECTS=1 /prefix/bin/who
linux-gate.so.1 (0xf060a000)
libsystemd.so.0 => not found
libpthread.so.0 => /usr/lib32/libpthread.so.0 (0xf05d6000)
libdl.so.2 => /usr/lib32/libdl.so.2 (0xf05d1000)
