More love for shared libraries in Samab4.
Now Samba4 binaries can start, althogh we get warnings from ld.so due
to the fact those libraries are both linked to system libkrb5 and to
libkrb5-samba4:

smbpasswd:/usr/lib/libcom_err.so.18.0: /usr/local/lib/libkrb5-samba4.so.0.0 : WARNING: symbol(krb5_acc_ops) size mismatch, relink your progr
am
(and so on).
