    iproute2: m_xt.so depends on dynsyms.list
    
    When doing parallel build on a fast machine with bottleneck in i/o,
    m_xt.so may start linking faster than dynsyms.list gets populated,
    resulting in error:
    
    ld:dynsyms.list:0: syntax error in dynamic list
    
    Fix this by adding dynsyms.list as make dependency to m_xt.so
    Described also here:
    https://bugs.openwrt.org/index.php?do=details&task_id=3353
    
    Change from v1:
    - add dynsysms.list dependancy only when shared libs are enabled

    Fixes: FS#3353
    (cherry-picked from commit edd53df16843a0a6380920ed17b88bfe7d26d71b)
