    Treat .eh_frame section before crtbeginT as normal input
    
    Force the exception frame section from input files before the crtbeginT
    file to be handled as an ordinary input section if we aren't creating
    the exception frame header.  If we don't do this, we won't correctly
    handle the special marker symbol in the exception frame section in the
    crtbeginT file.
    
    	PR gold/14675
    	* ehframe.cc (Eh_frame::add_ehframe_input_section): Force the
    	exception frame section from input files if it can't be

    	(Eh_frame::add_ehframe_input_section<64, true>): Likewise.

    	bool parameter to indicate if the exception frame section
    	can be optimized.

    	has_crtbeginT and optimize_ehframe_ to !has_crtbeginT.
    	(Layout::layout_eh_frame): Pass this->optimize_ehframe_ to
    	Eh_frame::add_ehframe_input_section.
    	(Layout::make_eh_frame_section): Set this->optimize_ehframe_
