Disable shared libraries on upcoming AIX/ia64

[Alexandre Oliva]

Some pending patches introduce support shared-library support for AIX
5, but only for AIX 5/power.  This means the upcoming release of AIX 5
for the AI64 platform, that uses a completely different linker and
shared-library model (ELF, thanks God! :-), would encounter a libtool
that doesn't support it.  I'm checking in these patches in MLB, HEAD
and 1.3 branch, so that we at least don't attempt to build shared
libraries on non-Power AIX platforms, to give volunteers time to
introduce appropriate shared library support.

The patch for ltcf-cxx.sh may look like utter non-sense, but it's
there so that it's not forgotten when the pending patch that
introduces C++ shared-library support is installed.
