"preload" ing xmpp solved the motif issue.

grep -v \; modules.conf

Just to be clear, 11.21.0-rc1 did _not_ have this issue before the upgrade and the rebuilding. Maybe some quirk with the new gcc version ?

Perhaps some modules didn't get rebuilt? Did you try to 'make uninstall-all' before building from a fresh tarball?  Obviously backup your configs. :)

I have a Fedora 23 VM so I'll upgrade it and see if I get any goofiness when building Asterisk.

In my build I'm running into:

{noformat}
gcc: error: /usr/lib/rpm/redhat/redhat-hardened-ld: No such file or directory
/root/asterisk/asterisk-11.21.0-rc1/Makefile.rules:170: recipe for target 'res_calendar_icalendar.so' failed
make[1]: *** [res_calendar_icalendar.so] Error 1
Makefile:394: recipe for target 'res' failed
make: *** [res] Error 2
{noformat}

I see the same issue for a few of the modules that didn't load for you. Did you run into this same issue ?

No , I didn't have any problems with the build. Simply preloading xmpp worked, using the same installation. That is, I installed the rebuilt rpm, and got the error. Then added preload xmpp to modules.conf. Did not rebuild, simply restarted asterisk, and all's well.

I didn't bother "preload"ing  res_calendar since I don't use it, but it seems to have built correctly:

rpm -qif /usr/lib64/asterisk/modules/res_calendar_icalendar.so

I finally had time to get back to this. I figured out what my issue was: ASTERISK-25726

Now I'll see if I can reproduce your issue again.

In 11.21 installed on Fedora 23 I only get issues with the following

{noformat}
[Jan 26 09:44:03] WARNING[21364] loader.c: Error loading module 'res_calendar_exchange.so': /usr/lib/asterisk/modules/res_calendar_exchange.so: undefined symbol: ast_calendar_register
[Jan 26 09:44:03] WARNING[21364] loader.c: Error loading module 'res_calendar_caldav.so': /usr/lib/asterisk/modules/res_calendar_caldav.so: undefined symbol: ast_calendar_event_container_alloc
{noformat}

For res_agi and the others (even chan_motif) I don't get an issue and I didn't need to preload res_xmpp..

I wonder what is different?
What options did you use when configuring and building?
Did you initially get those module loading errors with the default modules.conf?

Note: I'm also using gcc version 5.3.1 20151207 (Red Hat 5.3.1-2) (GCC)
