[PATCH] [PECOFF] Handle weak external symbols.

[Rui Ueyama]

Hi kledzik,

This is a second patch to show how I'm going to use the fallback mechanism
to implement COFF weak external symbols. What I'm doing in this patch is
adding a new field to COFFUndefinedAtom for a fallback atom and add a new
parameter to the constructor to pass an optional fallback atom.
