xsd2ttcn is hardcoded in makefile generator

Summary

The xsd2ttcn utility supports "-N" option (generate separate modules for each XSD with no target namespace). This behavior is expected by ETSI TTCN-3 tests. However, currently "xsd2ttcn" is hardcoded when generating Makefile.

It would be nice to have capability to specify some option to "makefilegen" utility and TPD to generate Makefile using "xsd2ttcn" with "-N" option.

Possible fixes

This is not a real fix. The patch just shows which places should be modified. Real fix should put "-N" option accordingly to "makefilegen" switch and some TPD option.
