Since python-3.2, there is a race condition building in parallel on AIX:

Consider these Makefile(.pre.in) rules:

$(BUILDPYTHON): ...
  $(LINKCC) ... $(LINKFORSHARED) ...

Modules/_testembed: ...
  $(LINKCC) ... $(LINKFORSHARED) ...

Modules/_freeze_importlib: ...
  $(LINKCC) ...

On AIX, the variables get these values:

LINKCC = $(srcdir)/Modules/makexp_aix Modules/python.exp ...
LINKFORSHARED = -Wl,-bE:Modules/python.exp ...

Now $(BUILDPYTHON) and Modules/_testembed may run in parallel, causing Modules/python.exp to be created by two instances of makexp_aix eventually running at the same time.

Attached patch fixes this problem for cpython tip (doubt supporting AIX 4.1 and earlier still is necessary).

Thank you!
