overriden at runtime (not enabled yet, but it works). This will
allow us to build Glibc with no or a minimal set of locales (which
cuts 70 MB from the installed size of Glibc). The locales that the
user actually needs can then be built separately and enabled by
setting the environment variable LOCALE_ARCHIVE. For instance, on
NixOS, we could set it to something like
/var/run/current-system/locale-archive. For setuid applications,
the variable is ignored.
This is especially useful on 64-bit systems, because there we tend
to have *two* copies of locale-archive (namely in the 32-bit and
64-bit builds of Glibc). Having only one copy allows at least 70 MB
to be cut from the NixOS installation CD.
