I try to change owership of symbolic link in do_install, but it doesn't work.

I use the recipes like below.
===
do_install_append () {
        touch ${D}${bindir}/chown-test
        ln -fs ${bindir}/chown-test ${D}${bindir}/link-to-chown-test
        chown -R -h user:user ${D}${bindir}/link-to-chown-test
        chown -R -h user:user ${D}${bindir}/chown-test
}
===

It seems that only ownership of symbolic-link was modified to root when copied to package-split.

The following is the copy process that causes this problem.
When os.lchown() is uncommented, it works fine for me.
- lib/bb/utils.py

...(snip)...

>                 os.unlink(dest)
>             os.symlink(target, dest)
>             #os.lchown(dest,sstat[stat.ST_UID],sstat[stat.ST_GID])
>             return os.lstat(dest)

I think this is a bug. Right?
