Bug 12991

Some packages create a symlink for gettext-tiny in
 .../per-package/PKGNAME/host/share

e.g.:

lrwxrwxrwx 72 matuschd matuschd   84 Jun  9 11:49 /home/matuschd/buildroot-4/per-package/xkeyboard-config/host/share/gettext -> /home/matuschd/buildroot-4/per-package/host-gettext-tiny/host/usr/share/gettext-tiny

However, cairo and fontconfig, create a directory with a subdirectory "its":

ls -l /home/matuschd/buildroot-4/per-package/python-pycairo/host/share/gettext
total 4
drwxr-xr-x 2 matuschd matuschd 4096 Jun  9 11:54 its


As the result, the final rsync fails as the directory is non-empty:

rsync -a --link-dest=/home/matuschd/buildroot-4/per-package/alsa-utils/host/ /home/matuschd/buildroot-4/per-package/alsa-utils/host/ /home/matuschd/buildroot-4/host
cannot delete non-empty directory: share/gettext
could not make way for new symlink: share/gettext
rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1196) [sender=3.1.2]
Makefile:737: recipe for target 'host-finalize' failed
make[1]: *** [host-finalize] Error 23
Makefile:84: recipe for target '_all' failed
make: *** [_all] Error 2

This way, the PER_PACKAGE_DIRECTORY setting can't be used 

I'm not sure at what point this should be fixed
