Closed issue by beginner3456789 on void-packages repository

https://github.com/void-linux/void-packages/issues/49162

Description:
### Is this a new report?

Yes

### System Info

Void 6.7.7_1 x86_64 GenuineIntel uptodate rrFFF

### Package(s) Affectedhttps://sourceware.org/glibc/wiki/Proposals/C.UTF-8

glibc-locales-2.38_5 GNU C library - locale data files

### Does a report exist for this bug with the project's home (upstream) and/or another distro?

commented at https://github.com/archlinux/mkinitcpio/commit/5db56e248463033f3d70f192d517498e906b2569

### Expected behaviour

The mkinitcpio was changed to locale C.UTF-8 except the /etc/default/glibc-locales doesn't have that choice. So I had to add the choice `C UTF-8` to the /etc/default/glibc-locales and now there are no errors with mkinitcpio:
```
$ xbps-reconfigure -f glibc-locales
glibc-locales: configuring ...
Generating GNU libc locales...
  en_US.UTF-8... done.
  en_US.ISO-8859-1... done.
  C.UTF-8... done.
glibc-locales: configured successfully.

```

### Actual behaviour

### Steps to reproduce

This problem maybe only affects mkinitcpio and started after updating mkinitcpio from v37.3 to v38 and installing kernel 6.7.7_1. Then downgrading to mkinitcpio 37.7 returned the error free behaviour. Then adding the `C UTF-8` choice to /etc/default/glibc-locales allowed installing mkinitcpio 38 and kernel 6.7.7_1 without the above errors about the "cannot change locale". 

So glibc 2.35 changes about C.UTF-8 need to appear in the locales. This should be easy to fix except I am unsure about the correct syntax for the C.UTF-8 entry in the /etc/default/glibc-locales. For reference: https://sourceware.org/glibc/wiki/Proposals/C.UTF-8
