Subject: [PATCH] ipvsadm: allow to redefine AR (libipvs)
Date: Sat, 5 Feb 2022 00:52:15 +0300

libipvs Makefile uses `ar` to build archive. On cross-compile
cross-platfrom build it fails due system ar might be incompatible
with the objects generated by $(CC). It happens if build ipvsadm
on macos using GCC Toolchain (Linux target)
This patch allows to redefine `ar` using AR var in libipvs Makefile
