bug#25775: Can't install packages after guix pull

[sirgazil]

Hi,

I've been using the binary installation of Guix on Debian 8 for some time now. However, after a "guix pull", I can't install packages anymore.

Steps to reproduce

===============

1. Run "guix pull" as a user
   
2. Run "guix package -i guile"
   

Expected result

============

The latest stable version of GNU Guile is installed correctly.

Unexpected result

==============

I get the following error:

warning: failed to install locale: Invalid argument

System information

===============

Guix (after pull): guix (GNU Guix) 20170216.20

Foreign distro:

Debian 8 (Linux makina 3.16.0-4-686-pae #1 SMP Debian 3.16.39-1 (2016-12-30) i686 GNU/Linux)

Additional notes

=============

There is a related conversation about this problem in #guix log (https://gnunet.org/bot/log/guix/2017-02-17#T1295254) where amz3` reported the same problem on Ubuntu 16.10 (amd64). lfam couldn't reproduce the problem on x86_64 Guix on Debian.

It was suggested by lfam in the same conversation that the problem might be due to a very old guix-daemon, which is true for my system. However, there was no way for me to update the daemon because I get the same error described above when I run the second step of the following procedure (run as root):

1. Run "guix pull"
   
2. Run "guix package --upgrade"
   
3. Restart guix-daemon
