    libstdc++: Reduce output of 'make check'
    
    This removes the 39 lines of shell commands that get echoed when
    starting the testsuite. The fact that near the end of that output it
    prints `echo "WARNING: could not find \`runtest'" 1>&2; :;` makes it
    look like that warning is actually being shown to the user.
    
    Suppress echoing the recipe, so that users only see the actual output
    from the testsuite, not the makefile recipe as well.
    
    libstdc++-v3/ChangeLog:
    
            * testsuite/Makefile.am (check-DEJAGNU): Use @ in recipe.
            * testsuite/Makefile.in: Regenerate.
