I have experienced the same problem under ppc64 aix 6.1.2.0 while compiling
Python 2.7.1
$ cd Python-2.7.1
$ mkdir __build
$ cd __build
$ ../configure --with-gcc=xlc_r --with-cxx-main=xlC_r --with-threads
--disable-ipv6

-L/opt/freeware/lib -L/usr/local/lib -o build/lib.aix-6.1-2.7/_struct.so
unable to execute ../Modules/ld_so_aix: No such file or directory
There are references to $(srcdir)/Modules/ld_so_aix in both configure.in and
Makefile.pre.in whereas ld_so_aix is created in build tree.

==================================================
After fixing these 2 files, Modules/ld_so_aix is found and properly executed by
compilation process, but then there is a new issue:
Modules/ld_so_aix xlc_r -bI:Modules/python.exp -L.. -L/opt/freeware/lib
-L/opt/freeware/lib
build/temp.aix-6.1-2.7/data/tcarel/Python-2.7.1/Modules/_struct.o
-L/opt/freeware/lib -L/usr/local/lib -o build/lib.aix-6.1-2.7/_struct.so
Modules/ld_so_aix[183]: Modules/makexp_aix: not found.
This time, makexp_aix is expected to be is the same directory than ld_so_aix
whereas makeexp_aix remains in the source tree.
Here is a fix:
==================================================
diff -r f4e6e18cae4b Modules/ld_so_aix.in

==================================================
The first value fix the issue while building Python. The second will use PATH
to find makeexp_aix as explained in section `SHARED LIBRARY SUPPORT' in
AIX-NOTES (for building shared extension modules).
You can find a patch for 2.7 branch in attachment.
