Hi!
I've been surprised that
make check-c++1z RUNTESTFLAGS=dg.exp=direct-enum*
attempts to run the whole testsuite in -std=c++1z mode,
while if I replace check-c++1z with check-g++ or check-c++-all,
it works properly.
The following patch passes the var down to the submake, so that it works
as expected. Ok for trunk?

* Make-lang.in (check-c++1z): Pass RUNTESTFLAGS down to
make check-g++.
