Hi Zbigniew, nice to meet you at Flock.

== Summary ==
glibc-minimal-langpack is added to @Buildsystem group and installed
into the minimal buildroot instead of glibc-all-langpacks. Packages
which need more locales than plain C/C.UTF-8/POSIX need to pull them
in through BuildRequires.

I think not installing  glibc-all-langpacks by default in the Koji buildroot makes good sense but how about replacing it in the first instance with glibc-langpack-en?

A quick grep over spec files reveals:
```
$ rg -l 'LC_CTYPE=[^C]' *.spec | wc -l
11
$ rg -l 'LC_ALL=[^C]' *.spec | wc -l
42
```

Also:
$ grep -l -e LANG=en *.spec | wc -l
99
