[PATCH] Do not test undef symbols across shlibs on AIX.

On AIX, undefined symbols across shared libraries can work only when
the main program explicitly exports those symbols. As this is bad
practice anyway and -no-undefined should be preferred, we skip this.
* tests/template.at: Skip test with undef syms across libraries on AIX.
