gold patch committed: Handle odd section symbols with -r

[Ian Lance Taylor]

The last case in PR 7091 is about a section symbol for a SHT_REL section
when linking with -r.  Such a case can not be generated by current
versions of gas.  However, they are valid ELF.  gold was crashing trying
to determine the value to use for such a section symbol.  In fact gold
will never emit the section symbol, and it would be bizarre in the
extreme if a relocation entry referenced the symbol.  However, there is
no need to crash.  I committed this patch to fall back to using the
start of the output section as the address for such a section symbol.
This is not really right, but then nothing is really right if anything
actually needs the value of the symbol.
