There are 2 patches in this series, and the first one is needed to
avoid the recursive dependency problem  from showing up (it's a
necessary workaround for now).

Patching Makefile of dnsmasq itself is necessary for the build system
of OpenWrt and Makefile of dnsmasq to pick up a possibly updated
config of dnsmasq-full variant. Otherwise rebuild of dnsmasq-ful may
not happen as expected when users enable or disable a feature with
e.g. make menuconfig.
