[OpenWrt-Devel] [PATCH] iproute2: m_xt.so depends on dynsyms.list

[Roman Yeryomin]

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:
