With this change, we are no longer passing --without-python when
BR2_PACKAGE_UTIL_LINUX_LIBMOUNT is disabled. I think it would be good
to continue passing --without-python. Also, shouldn't python be built
before util-linux for this to work ?

Would something like this make sense maybe:

ifeq ($(BR2_PACKAGE_PYTHON)$(BR2_PACKAGE_PYTHON3),y)
UTIL_LINUX_CONF_OPTS += --with-python
UTIL_LINUX_DEPENDENCIES += $(if $(BR2_PACKAGE_PYTHON),python,python3)
ifeq ($(BR2_PACKAGE_UTIL_LINUX_LIBMOUNT),y)
UTIL_LINUX_CONF_OPTS += --enable-pylibmount
else
UTIL_LINUX_CONF_OPTS += --disable-pylibmount
endif
else
UTIL_LINUX_CONF_OPTS += --without-python
endif

Thomas
