That's not a backtrace, because bfd_final_link() is not a function.
It is a macro, and I am trying to find out what the real function is.
The easy way to get a backtrace is to use gdb.

The linker is supposed to call lang_common() to allocate all the
common symbols.  That sets the hash table entry to be a defined
symbol.  If you are using the generic linker, as seems likely, then
set_symbol_from_hash() is called on each symbol to set it to the hash
table entry.  The result is that coff_XXX_reloc() should never see a
common symbol.  It should only see defined symbols.

That is how it is supposed to work.  I think you are going to have to
debug the rest of this yourself.  Find out if any of those steps is
not happening.
