This will reduce the system closure size by about 200MB under NixOS by sharing the glibcLocales package. When home-manager is installed on Linux without the NixOS module, all glibc locales are installed, as before. Resolves: #2333

# The glibc package in Nixpkgs is patched to make it possible to specify
|
|
# an alternative path for the locale archive through a special environment
|
|
# variable. This would allow different versions of glibc to coexist on the
|
|
# same system because each version of glibc could look up different paths
|
|
# for its locale archive should the archive format ever change in
|
|
# incompatible ways.
