commit 7bdb5a1d056667ef28586f12a62db3a660c94ff1
Author: Mathieu Othacehe <address@hidden>

    gnu: glibc: Export supported locales.
    
    Debian and Archlinux (at least) force the installation of the
    localedata/SUPPORTED file of the glibc. This file lists all the supported
    locales of the glibc.
    
    * gnu/packages/patches/glibc-supported-locales.patch: New file.
    * gnu/local.mk (dist_patch_DATA): Add it.
    * gnu/packages/base.scm (glibc/linux): Add the previous patch,
    (glibc-2.28): ditto.
