Ferruh Yigit 9f8eeb60ef mk: fix combined lib build with ABI versioning
Fixes following error (observed when versioning macros used):
  LD libdpdk.so
  /usr/bin/ld: /root/dpdk/build/lib/libdpdk.so: version node not found
  for symbol <function>@DPDK_x.y

Also resulting combined library contains symbol version information:
$ readelf -a build/lib/libdpdk.so | grep rte_eal_ | grep @ | head
   <...>    GLOBAL DEFAULT   12 rte_eal_alarm_set@@DPDK_2.0
   <...>    GLOBAL DEFAULT   12 rte_eal_pci_write_config@@DPDK_2.1
   <...>    GLOBAL DEFAULT   12 rte_eal_remote_launch@@DPDK_2.0
...

Versioning fixed by merging all version scripts into one automatically and
feeding it to final library.
