[dpdk-dev] [PATCH v3] mk: fix acl library static linking

Since below commit, ACL library is outside the scope of --whole-archive
and ACL autotest fails.

  RTE>>acl_autotest
  ACL: allocation of 25166728 bytes on socket 9 for ACL_acl_ctx failed
  ACL: rte_acl_add_rules(acl_ctx): rule #1 is invalid
  Line 1584: SSE classify with zero categories failed!
  Test Failed

This is the result of the linker picking weak over non-weak functions.

Fixes: 95dc3c3cf31c ("mk: reduce scope of whole-archive static linking")
