Add option --weak-unresolved-symbols to treat unresolved symbols as weak ref.
This patch adds option --weak-unresolved-symbols to treat unresolved symbols as
weak references. This is helpful when we want the link to succeed with unresolved
symbols and the dynamic loader to not complain at run-time. Option
--warn-unresolved-symbols lets the link succeed but could fail at run-time with
unresolved symbol warnings especially when the unresolved symbols have GOT entries
and dynamic relocations against them, like when -fPIE is used.
