Here. Tested on Linux-x64. I made the test for the macro value compare
it relatively rather than exactly;
I don't think our tests should necessarily break just because a macro

    Add a feature macro for C++17 make_from_tuple.
    * include/std/tuple (__cpp_lib_make_from_tuple): New.
    * testsuite/20_util/tuple/make_from_tuple/1.cc: Adjust.
