Cross compile click packages

Hey,

does anybody cross compile click packages?

If i cross compile click with the default prefix, but install it to a
different location for further usage with click packages, the file
config.mk in clickdatadir contains the original prefix. This is fine to
define the directories for the final destination locations of the
packaged to be cross compiled, but the package Makefiles use this
information to find the installed click instance, too. One can configure
a package with --with-click=PREFIX, but this doesn't help.

I know that i can compile click with local elements instead of packages,
but using packages is a cleaner way, i think.

Are there any special configure flags or something similar i am missing,
to get click packages cross compiled?

Regards,
Sascha
