In terms of Makefile, nothing else needs to be done than just the final:

$(eval $(call AUTOTARGETS,package,util-linux-ng))

in the util-linux-ng.mk file.

This needs to be

UTIL_LINUX_NG_VERSION=2.17

I'm not sure this test is going to work. It should probably be

ifneq ($(UTIL_LINUX_NG_PATCHLEVEL),)

Get rid of thse four variables.

This empty variable is not needed.

here you should add
       UTIL_LINUX_NG_DEPENDENCIES += ncurses

to make sure ncurses gets compiled before util-linux-ng, when both are
enabled in the config.

The test ifeq ($(BR2_USE_WCHAR),n) is not going to work. When options
are not enabled, their value is empty, not "n". So this test should be :

	ifneq ($(BR2_USE_WCHAR),y))

Moreover, I haven't thought about it, but I don't see why WCHAR is
playing a role here.

Last thing: in the rest of the Buildroot code, we don't do much this
kind of indentation and marking of endif with the initial condition.
Maybe we should, but we don't at the moment.

Same thing as above, should be :

 ifeq ($(BR2_PACKAGE_ZLIB),y)
   UTIL_LINUX_NG_DEPENDENCIES += zlib
 else
   UTIL_LINUX_NG_CONF_OPT+=--disable-cramfs
 endif

Quite probably because of your variables being named
UTIL-LINUX-NG_something instead of UTIL_LINUX_NG_something.
