[PATCH][gold] Fix the value of "dot" symbol in an empty section.

Hi,

gold may assign an invalid value to symbol "dot" in a rare case when
the section, where the assignment is located, is empty, and, at the
same time, some orphan sections are put just before it. In that case,
you will get different values if you take the value of "dot" symbol
inside the section or if you take ADDR of it.

Best regards,
Igor Kudrin
