MIT Kerberos 5 1.10.2 and OpenSSL want dlinfo; while OpenSSL supports
systems without dlinfo, Kerberos requires it on any non-Windows
systems (Windows has an equivalent API).
AFAICT the file that it occurs in must be built.

+ OpenSSL required dladdr on my musl test system for dynamic engine
loading (but no dlinfo requirement seen).

Have you looked into what it's used for? I'm not 100% rejecting it at
this time, but I really dislike the dlinfo interface. It exposes a lot
of internals that applications should not be inspecting and seems to
require us to keep around extra bloated data structures that are not
otherwise needed.

(As noted by orc, it isn't strictly dlinfo that openssl needs, but
dladdr; all the musl distros have a patch to disable this)

Here, the function name says it all:
module_get_filename_for_symbol
It occurs in src/util/verto/module.c in Kerberos 5 1.10.2.
I may email the Kerberos ml to inquire about this...
