wsdiff should ignore .SUNW_dof
the .SUNW_dof ELF section is not reproducibly built (some of the information comes from uses of ftok(3C) on object files to create unique values).
wsdiff should ignore it as inconsistent (as it already does to certain other sections).
Open question: Can a binary differ both meaningfully and only in its .SUNW_dof? If so, such a change would be inappropriate, and we're stuck.
