Does this explanation make sense?
http://debbugs.gnu.org/cgi/bugreport.cgi?bug=22402#37

If so, then you should read the warnings and investigate which files are
colliding. Some, like the hicolor icon-theme.cache, seem harmless to me,
although I welcome a second opinion.

I don't know about this one. Files the .la extension are used by libtool
but I don't have enough experience with libtool or know enough about
libatomic to know if this is going to be a problem.
