Many of these failures are caused by glibc 2.38 now having strlcat and
friends, and this causes a dpkg-gensymbols error like this (example
from src:libqb):
dpkg-gensymbols: error: some symbols or patterns disappeared in the
symbols file: see diff output below
dpkg-gensymbols: warning: debian/libqb100/DEBIAN/symbols doesn't match

Do we have a pattern to fix these, or a checklist? Mark them as
optional I suppose, but how can we be sure reverse dependencies aren't
relying on these strl* symbols, do we rebuild them all? It may sound
far fetched, but I suppose some application could have been relying on
strlcat from bin:libqb100 (even though it's not declared in
libqb-dev's /usr/include/qb/* anywhere).
I saw the fix[1] to krb5's build issue, but there the symbol was
internal (but still exposed?). Is that what we need to apply,
including the replacing of #MINVER# in the symbols file to a strict
"equals", which is what I assume changes the shlibs:Depends from a ">=
MINVER" to "= $ver", and thus accounts for the ordering of upgrades?
And still a breaks for the other binary packages produced by the same
source?
