Is that without or with runtimelinking enabled (LDFLAGS=-Wl,-brtl passed
to configure)?  If without, then libtool puts the modcpu.so file into
the modcpu.a archive (the way AIX does with its system modules as well)
and that is to be expected.

With runtimelinking, the .so file should be a separate file.

BTW, you didn't specify any bug or misbehavior that you see, so maybe
everything else works as expected?

Well, I really don't know the differences between libtool-1.5.26-1 and
libtool 1.5.26-4 (this really all is a libtool issue, not an Automake
one), but if there were bugs in either, I'd first ask you to retry with
2.2.6b anyway.

This is a pretty sure sign that you have mixed up macros from one
Libtool version with a ltmain.sh file from another Libtool version.
Perchance your aclocal.m4 or acinclude.m4 files contain old Libtool
macro definitions?
