    libstdc++: Add new-abi-baseline target to main Makefile
    
    This allows you to run 'make new-abi-baseline' in the
    $target/libstdc++-v3 build directory instead of only in the testsuite
    subdirectory.
    
    libstdc++-v3/ChangeLog:
    
            * Makefile.am (new-abi-baseline): New target.
            * Makefile.in: Regenerate.
