[Nut-upsdev] 2.7.4 make install fails: libnutclient.so.0.0.0 missing

[Roger Price]

I upgraded an operating system to openSUSE 42.2, kernel 4.4 and recompiled 
nut 2.7.4.  ./configure, make clean and make went well, but make install 
failed. Make reports

This compilation and installation worked with the previous version of the 
OS.  I'm probably doing something stupid, but for the moment I don't see 
what it is. Any suggestion would be very welcome.
