[yocto] Where should I append Yocto bitbake task to create work folder symlink ?

[Woronicz, Bartosz ( NSN - PL/Wroclaw)]

Let's say I have my package at

     host-64/tmp/work/x86_64-poky-linux/mypackage/1.2.3-r4/

I would like to have symlink created

     host-64/tmp/work/x86_64-poky-linux/mypackage/latest -> 1.2.3-r4/

each time the new version is fetched and unpacked. How can I achieve 
that ? Which class, task should I append, extend ?

Optionally, I would like to have that for all packages or at least 
packages in my meta.


P.S. I asked the same question here:
