Works here:

  dima@scrawny:/tmp/gnuplot-main/src$ make -n timestamp.h
  echo Making timestamp.h
  echo "#ifndef GNUPLOT_TIMEBASE_H_INCLUDED" >timestamp.ht
  echo "#define GNUPLOT_TIMEBASE_H_INCLUDED" >>timestamp.ht
  echo "const char gnuplot_date[] = \"`git log -1 --format=%ci | cut -b-11`\";" >>timestamp.ht
  echo "#endif /* GNUPLOT_TIMEBASE_H_INCLUDED */" >> timestamp.ht
  if cmp -s timestamp.h timestamp.ht; then rm -f timestamp.ht; else mv timestamp.ht timestamp.h; fi

  dima@scrawny:/tmp/gnuplot-main/src$ make timestamp.h 
  Making timestamp.h

  dima@scrawny:/tmp/gnuplot-main/src$ cat timestamp.h 
  #ifndef GNUPLOT_TIMEBASE_H_INCLUDED
  #define GNUPLOT_TIMEBASE_H_INCLUDED
  const char gnuplot_date[] = "2018-02-11 ";
  #endif /* GNUPLOT_TIMEBASE_H_INCLUDED */

  dima@scrawny:/tmp/gnuplot-main/src$ git log -1 --format=%ci | cut -b-11
  2018-02-11 

Which part of that is different for you? Note that this logic changed
