Note that there is no guarantee that a new glibc version actually has any
symbols in libc at the corresponding symbol version (there are no
GLIBC_2.20 symbols in any ABI test baseline for any architecture, for
example). If it happens not to, will the symbol version exist at all to
satisfy this check?
