Hi,
AIX noob here :(
Can someone please help me figure out why this fails:

I have no access to an AIX box, so have no chance to debug this. Google
said that this could be because of linking order, but vlprocs.c is
already using afsconf_SuperUser which is in the same file as the new
afsconf_CheckRestrictedQuery. So this seems strange to me.
The AIX builder is the only one in the current set of "triggered" builders
(triggered for each gerrit submission) that enforces library export lists
when building executables. The OS X builders would also do so, but were
disabled since a compiler update added more -Werror behavior that
triggered on our code.
The fix is to export the afsconf_CheckRestrictedQuery from liboafs_auth
and/or libafsauthent (as appropriate), by adding it (sorted
alphabetically) to the files liboafs_auth.la.sym and/or
libafsauthent.la.sym, as appropriate. The dependencies in the root
Makefile.in suggest that libafsauthent is the relevant one for this
executable, but I don't remember enough of the distinction between the two
to guarantee that the new symbol will not need to be exported from both of
the auth libraries.
