Well, GLIBC_PRIVATE is a private glibc interface intended for use by
various parts of glibc itself, it can change (and does change from time
to time) without providing backwards compatibility, any symbol in
GLIBC_PRIVATE can disappear or change its semantics during glibc update.
Consequently, packages are not allowed to have dependencies on
GLIBC_PRIVATE.
