See below at the end.  Did you ever confirm by the way that this was a
regression in Libtool, and that it wasn't due to, say, a change in
compiler version or setup?  That should be the first step, before
starting bisect.

I have 4.2.4, too, but it may be modified by the vendor.  It seems to
have -blibpath set at configure time, but I don't think that should
translate to a setting at run time:

No, but the test in libltdl/m4/libtool.m4:_LT_SYS_MODULE_PATH_AIX sets
lt_cv_aix_libpath='/opt/fsw/gcc42/lib/gcc/powerpc-ibm-aix5.3.0.0/4.2:/opt/fsw/gcc42/lib/gcc/powerpc-ibm-aix5.3.0.0/4.2/../../..:/usr/lib:/lib
   ...'

(see config.log or config.cache).

Cheers,
Ralf
