gold patch committed to 2.20 branch: --no-add-needed

[Ian Lance Taylor]

One way to make sure that a program links with both GNU ld and gold is
to use the --no-add-needed option.  That will make GNU ld avoid
looking in indirectly referenced shared libraries, as gold always
does.  However, binutils 2.20 has the annoyance that gold does not
support the --no-add-needed option.  I copied this patch from mainline
to 2.20  branch to avoid that annoyance.
