fact that we are adding a dependency on a native package for just glibc 
based images is what I was asking about. libc-glibc is a target specific 
override and therefore this makes it such that it is only needed when 
target is glibc which to be sounds wrong, since other libcs should have 
same dependency needs as well.

Guessing from your error message it seems somewhere crash build is 
depending upon id program and this id program is coming from 
coreutils-native, which seems to depend on this library so this 
dependency really belongs there, it seems to me that coreutils-native 
should depend upon
libnss-nis-native
