This old syntax was correct -- if it was broken, it is a bug.

The "double variant" syntax is used to create a variant that will be  
applied *instead of* two singular variants. That is, if both "darwin"  
and "kerberos" are selected, then the "darwin kerberos" variant will  
be used instead of individual darwin {} and kerberos {} variants.
