    Fix incremental linking failure with GCC 7+.
    
    With the new compiler, we're running out of patch space for the .eh_frame
    section. To workaround that issue, we compile the before and after versions
    both with no unwind tables.

    	PR gold/22309
    	* testsuite/Makefile.am (two_file_test_1_v1_ndebug.o): Compile with
    	no EH information.
    	(two_file_test_1_ndebug.o): Likewise.
    	* testsuite/Makefile.in: Regenerate.
    	* testsuite/two_file_test_1.cc: Touch to force recompilation with new
    	flags.
    	* testsuite/two_file_test_1_v1.cc: Likewise.
