Yeah, it's kind of a problem that the libroken ABI isn't stable depending
on what facilities are available on the local system, although it looks
like the only other package in Debian that uses it is openafs.

I think the options are to either bump the SONAME for the dropped symbol,
or add an rk_closefrom wrapper around the glibc closefrom to keep the same
ABI.  (Or break the ABI without changing the SONAME on the grounds that
only a few packages use it, but I'm pretty hesitant to recommend doing
that since who knows what outside of Debian might break and we try hard
not to do that.)

What would be considered an acceptable solution here?

Presumably I can't just delete the symbol, that might break stuff.

Bug#1016884: heimdal: FTBFS with glibc >= 2.34

[Samuel Thibault]

Source: heimdal
Version: 1.6~rc2+dfsg-9+deb8u1
Severity: serious
Justification: FTBFS

Hello,

Now that glibc provides a closefrom function, heimdal doesn't build its
own rk_closefrom function any more, and thus the
libroken18-heimdal.symbols check complains:

- rk_closefrom@HEIMDAL_ROKEN_1.0 1.4.0+git20110226
+#MISSING: 7.7.0+dfsg-4+b1# rk_closefrom@HEIMDAL_ROKEN_1.0 1.4.0+git20110226
