Let us override the examples directory using --with-examplesdir=DIR.
This is handy for NetBSD where HDF5 examples are installed
by convention in $prefix/share/examples/hdf5/ rather than in
${prefix}/share/hdf5_examples/, which is the HDF5 default.
Place hdf5_examples/ under ${datarootdir} which on most systems will be
${prefix}/share/, anyway.
