 Because that check is within

ifeq ($$($$($(2)_KCONFIG_VAR)),y)
...
endif

and these packages are host-only packages.

 It has to be within that condition, since the _SITE may be set only or
differently based on kconfig options which are only set when the package is
selected. I tested and it fails for instance on arm-trusted-firmware if that
package is not selected.

 We need Config.in.host :-)
