I agree this looks like you used an older localedef that doesn't support 'codepoint_collation'
as a new directive to enable C.UTF-8 with zero collation rules (strcmp/wcscmp sorting).

This is the error I get when I use glibc 2.33 to compile the glibc 2.34 C.UTF-8:

[carlos@athas glibc-rawhide]$ LOCPATH=/home/carlos/install/glibc-pristine/usr/lib64/locale I18NPATH=/home/carlos/src/glibc-pristine/localedata/ localedef -f UTF-8 -i C /home/carlos/install/glibc-pristine/usr/lib64/locale/C.UTF-8
/home/carlos/src/glibc-pristine/localedata//locales/C:60: LC_COLLATE: syntax error
/home/carlos/src/glibc-pristine/localedata//locales/C:61: LC_COLLATE: empty category description not allowed
[error] too many errors; giving up
[carlos@athas glibc-rawhide]$ echo $?
1

Which is exactly what is expected. We have a new directive and you must use the new localedef
to compiled the new locale.
