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. gold/ 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.
