Configuration

Option -nostdinc++ is added to CXXFLAGS. That is due to bug:

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100017

Original bugreport describes the problem during the build of the whole gcc, but here it reproduced for standalone libstdc++. 

src_config()
{
    mkdir -v build
    cd build

    ../libstdc++-v3/configure       \
    CXXFLAGS="-g -O2 -D_GNU_SOURCE -nostdinc++"  \
    --prefix=${PREFIX}              \
    --disable-multilib              \
    --disable-nls                   \
    --host=$(uname -m)-lfs-linux-gnu \
    --disable-libstdcxx-pch
}

Compilation

src_compile()
{
    make ${MAKEOPTS}
}

Installation

{
    make install ${MAKEOPTS} DESTDIR=${D}
