BFD patch for linker version stamp

This patch enables real version stamp into produced PE binaries.

The PE version of the linker have injected the linker version "2.56"
into all produced binaries since beginning of time. This makes it
impossible to judge status of the tools that produced an unknown binary.
A correct linker version stamp could help debugging tools, security
and binary information tools.
