Sanity check for duplicate PACKAGE_ARCHS

From: Joshua Lock <[email protected]>

I have had some pain this morning caused by duplicated entries in my PACKAGE_ARCHS variable. After Richard helped me debug this he suggest we add a sanity check for this issue.

Duplicate entries in PACKAGE_ARCHS causes problems with rootfs generation. For example multiple architecture entries in opkg.conf will confuse the opkg package manager.

Merged into master, not sure this will make bernard at this point but its good to have the check.
