I don't know about the rest, but this one sounds familiar to me. But IIRC 
this one was fixed semi-recently (1-2 years ago), while making 
--dynamicbase the default.

I think it was fixed in this binutils commit:

commit 514b4e191d5f46de8e142fe216e677a35fa9c4bb
Author: Jeremy Drake <sourceware-bugzilla@jdrake.com>

     Change the default characteristics of DLLs built by the linker to more 
secure settings.

This commit is included in binutils 2.36 and later.
