RFA: [dwarf2read.c] Avoid using section index if not yet set

[Fernando Nasser]

This fix was suggested to me by someone that loads symbols from object
files.  It seems that in this situation the section index may not be set
and this bit of code tries to use it.

I this fix correct?  Can I check it in?

Thanks.

Fernando



	* dwarf2read.c (new_symbol): Do not attempt to use the section
	index of a symbol if it is not yet set.
