[Bug 2031909] [NEW] tinydns: allocation failures with glibc 2.38/s390x

[Simon Chopin]

Public bug reported:

When using glibc 2.38, in some conditions tinydns fails with the
following error:

/usr/sbin/tinydns: error while loading shared libraries: libc.so.6:
cannot map zero-fill pages

This error shows up at least on the s390x autopkgtests for djbdns.

This is blocking the glibc transition.
