empty PACKAGE_CLASSES does not allow to use package-index

[skabanov]

For 2014.06 branch PACKAGE_CLASSES is set to " "
and because of this we can not use bitbake package-index to update index of ipk.
In package_manager.py generate_index_files function
we check this variable and because variable is not set we do not call
opkg-make-index.
Also we can not set PACKAGE_CLASSES in local.conf.

Thank you for fix. Is it possible to add it to 2014.06 branch also ?

This was fast.
