    i686: Fix build with --disable-multiarch
    
    Since i686 provides the fortified wrappers for memcpy, mempcpy,
    memmove, and memset on the same string implementation, the static
    build tries to optimized it by not tying the fortified wrappers
    to string routine (to avoid pulling the fortify function if
    they are not required).
    
    Checked on i686-linux-gnu building with different option:
    default and --disable-multi-arch plus default, --disable-default-pie,
    --enable-fortify-source={2,3}, and --enable-fortify-source={2,3}
    with --disable-default-pie.
