    tdf#142326: Adapt to "libstdc++: Implement LWG 1203 for rvalue iostreams"
    
    ...for libstdc++ 11.2, similar to 1f3dddd6f21d91c429190ae314dadeec409f35f4
    "Adapt to "libstdc++: Implement LWG 1203 for rvalue iostreams" for libstdc++ 12.
    The libstdc++ change referenced there has been backported to the releases/gcc-11
    branch past the releases/gcc-11.1.0 tag (i.e., only towards libstdc++ 11.2) as
    <https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=ca7d2f2ec9142995179a5d832a946b50de05e659>
    "libstdc++: Implement LWG 1203 for rvalue iostreams".
    
    According to
    <https://gcc.gnu.org/onlinedocs/libstdc++/manual/using_macros.html>,
    <https://gcc.gnu.org/onlinedocs/libstdc++/manual/abi.html#abi.versioning.__GLIBCXX__>,
    and <https://gcc.gnu.org/develop.html#timeline>, the right __GLIBCXX__ value for
    libstdc++ 11.1 should be 20210427, but at least
    libstdc++-devel-11.1.1-1.fc34.x86_64 defines it as 20210428 while not including
    the above "libstdc++: Implement LWG 1203 for rvalue iostreams" commit, so use
    that value here.
