Hello,

krb5 fails to build against glibc 2.38:

dh_makeshlibs -plibkafs0-heimdal -- -c4
dpkg-gensymbols: error: some symbols or patterns disappeared in the symbols file: see diff output below

and similarly in libroken19-heimdal.symbols.

strlcat and strlcpy were indeed added to glibc in version 2.38, so it's
not surprising that heimdal doesn't define its internal versions any
more.

I checked all *_amd64.so packages, apparently libafsauthent2 is using
rk_strlcpy and rk_strlcat from libroken, so a Breaks transition is
needed for that.
