Hmm ... I'm far from an expert on the packaging of locale data, but
the simplest explanation I can think of is that the tr_TR locale exists
to some extent on your machine but the LC_TIME component of that is
missing.

Do you get different results from "date" depending on the locale?
I get

$ LANG=C date
Sat Mar  7 21:44:24 EST 2020
$ LANG=tr_TR.utf8 date
Cts Mar  7 21:44:26 EST 2020

on my Fedora 30 box.

Another possibility perhaps is that you have partial locale settings
in your environment that are bollixing the test.  Try

$ env | grep ^LANG
$ env | grep ^LC_

If there's more than one relevant environment setting, and they
don't all agree, I'm not sure what would happen with our
regression tests.

BTW, what platform are you using anyway?
