Fedora Core/RHEL uses rpm's %{version}-%{release} there instead, so
something like:
ld --version
GNU ld version 2.17.50.0.6-2.fc6 20061020

-%{release} was added there for similar reason why you are adding date
- otherwise if the same version, but not really identical libbfd
is installed, building a new binutils can die horribly because
the newly built ld is run against installed libbfd.
