PATCH: Correct handling of R_ARM_RELATIVE on Symbian OS

[Mark Mitchell <mark at codesourcery dot com>]

My earlier patch for the handling of R_ARM_RELATIVE on Symbian OS, was
incorrect.  In particular, I used the incorrect section symbol.
Instead of locating the dynamic symbol table entry for the section
from which the symbol originated, I used the non-dynamic symbol table
entry for the section to which the relocation applies.  Urgh.

Fixed with the attached patch, which I committed as obvious.
