    libstdc++: use lt_host_flags for libstdc++.la
    
    For platforms like Mingw and Cygwin, cygwin refuses to generate the
    shared library without using -no-undefined.
    
    Attached patch makes sure the right flags are used, since libtool is
    already used to link libstdc++.
    
    libstdc++-v3/ChangeLog:
    
            * src/Makefile.am (libstdc___la_LINK): Add lt_host_flags.
            * src/Makefile.in: Regenerate.
