IIRC, this ChangeLog entry has nothing to do with this other check:

FWIW, it works for me on AIX 4.1.5.  I believe the different arises
from the fact that GCC's configuration headers for AIX 4.3 and above
define HAS_INIT_SECTION, so collect2 doesn't collect init symbols.  So
this test would only be meaningful for AIX up to 4.2.

Andrey Slepuhin <pooh@msu.ru>, who introduced this test, would
probably know.  In fact, I have probably already asked him this
question.  You may be able to find the answer in the archives of some
libtool mailing list, at http://mail.gnu.org/pipermail
