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.
