        exclude_libs_test_DEPENDENCIES): Add alt/libexclude_libs_test_3.a
        (exclude_libs_test_LDFLAGS): Add linker option
        -Wl,--exclude-libs,libexclude_libs_test_3

        (alt/libexclude_libs_test_3.a): New make rule.
        * testsuite/Makefile.in: Regenerate.
        * testsuite/exclude_libs_test.c : Declare lib3_default().
