let read_res add structure even in non-resonance case

The method read_res is often called first. If the LRP flag for
the material is -1, there's no resonance data, and the method did not
change anything.
However other methods expects _read_res to set structur[nuc]['data'],
added function to fill it with a single entry for mat_id and empty values

Fix the case where HDF5_LIBRARIES begins with DEBUG.  Allows bilder configuration line.  Add an option --moab to specify location of moab.  Not yet finding that, but now gets past configure.
Finds moab when specified on build line.  Puts the moab library directoy into link directories.
Better way of getting libgcc_s on Darwin.
Fix version.
Remove empty logical block.
