I *suspect* the base file was created as classic tiff, but the overviews
pushed the file size over the 4GB limit.  There is no way (with libtiff)
to transform a classic tiff file into BigTIFF "in place".  You could try
translating the base file to BigTIFF by adding the -co BIGTIFF=YES
creation option for gdal_translate.  Then gdaladdo ought to work.
