Bugzilla Bug 220871

Using the new 2008.0 profile scheme, autounmask is not able to determine the
correct arch token any more. This results in an endless loop adding entries
into /etc/portage/package.keywords like:

category/app-Maj.min ~

Notice the missing arch token after the '~'.

Reproducible: Always

Steps to Reproduce:
1. Use new 2008.0 profile on a stable box
2. Try to autoumask some ~ marked package
3. Watch your package.keywords grow with malformated entries



Expected Results:  
autounmask behaving correctly
