Beniamino, could you look into that?

In my opinion the current way of testing this is correct, since we
don't need to know if dhcpcd actually was built with IPv6 support, but
only if it supports the '-4' flag (that we pass to disable IPv6) and I
guess this depends only on the program version.

A potential problem is that IPv6 support in dhcpcd can be set from
configure script only when the executable path is autodetected (--with
-dhcpcd=yes) and not when a path is specified. So switching to runtime
detection could make sense; if you agree I will open an issue on
bugzilla for that.
