I'm a bit uncomfortable with this.  A few questions:

* Will your glibc patch reliably ensure that no functionality is lost
  because of picking up the wrong version of locales?

* Do we have a mechanism for automatically setting LOCPATH (or
  GUIX_LOCPATH) to include all of the available locale versioned
  subdirectories?
