I think that problem was fixed in Gnulib after tar 1.35 was released[1].
Although I don't have access to AIX 7.2, cfarm111.cfarm.net[2] does have
AIX 7.1 with GCC 8.3.0 and to verify my suspicion I reproduced the
problem as follows with tar 1.35:
./configure CC='gcc -maix64' ARFLAGS-crX64
make
I also confirmed that the problem does not occur with bleeding-edge GNU
tar, which I just now updated on savannah[3] to use current Gnulib (this
required a fixup[4] so that GNU tar no longer attempts to use
gettimeofday, which is removed in POSIX.1-2024).
