in the patch is different enough to fail to merge.
* gnu/packages/base.scm (make-glibc-locales)[source]: Add patch.
* gnu/packages/patches/glibc-locales.patch: Adjust for glibc 2.29 and move old
file...
* gnu/packages/patches/glibc-locales-2.28.patch: ...here.
* gnu/local.mk (dist_patch_DATA): Add it.
