[oe] perl warning on git connection via ssh

[Andreas Oberritter]

Dear admins,

whenever I connect to git.openembedded.org via ssh, I see the following
warnings:

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
	LANGUAGE = (unset),
	LC_ALL = (unset),
	LC_MESSAGES = "en_US.UTF-8",
	LANG = "de_DE.UTF-8"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").

You should be able to force the system default by removing "AcceptEnv
LANG LC_*" from sshd_config or by setting the four variables mentioned
above to "C" in the git user's profile.

Regards,
Andreas
