Maybe version.h should be moved.  I think oct-conf.h is only used by
code inside the libinterp directory.

In my build tree, I see the following generated header files:

  ./libinterp/version.h
  ./libinterp/interpfcn/graphics.h
  ./libinterp/interpfcn/defaults.h
  ./libinterp/oct-conf.h
  ./libinterp/interp-core/mxarray.h
