PATCH: PR gold/14675: No eh_frame info registered in exception_static_test

[Cary Coutant]

> Any progress?

I've committed the attached patch to fix this problem by delaying the
attachment of the optimized .eh_frame sections to the output section
until we see the end marker section (or to the end of pass 1 if we
never see an end marker).
