When c-ares was compiled before, libeXosip2 will use it as optional
dependency:
$ output/host/usr/bin/x86_64-linux-readelf -a output/target/usr/bin/sip_reg | grep NEEDED | sort
0x0000000000000001 (NEEDED) Shared library: [libcares.so.2]
[...]
The build system offers no option to en-/disable c-ares support:
