[OE-core] update-alternatives questions

[Andreas Müller]

Hi

when starting a fresh image (angstrom/opkg) I see for xfwm4 (xfce window manager 
included in meta-oe)

S98configure[285]: //var/lib/opkg/info/xfwm4.postinst: line 2: update-
alternatives: command not found

I checked: 

* there is no  update-alternatives in my image
* update-alternatives is packed in update-alternatives-cworth (sub package of 
opkg) which is not part of my image

Isn't it required to have update-alternatives on the target because it is used 
in postinst- / and postrm scripts?
