[Buildroot] [PATCH 2/3] package/bind: disable cmocka

[Raphael Pavlidis]

Maybe we could make this dependency dynamically, if the 
BR2_PACKAGE_CMOCKA is enabled.

For Example:

ifeq ($(BR2_PACKAGE_CMOCKA),y)
BIND_CONF_OPTS += --with-cmocka
BIND_DEPENDENCIES += cmocka
else
BIND_CONF_OPTS += --without-cmocka
endif
