When installing this unsupported combination, some solutions might be:
- Change the /etc/SuSe-release: backup the original file and change it to SuSe 9.
- error invoking target of makefile ins_ctx.mk --> install gcc43-32bit
- error on ins_sysman.mk --> unset LD_LIBRARY_PATH
- error on ins_emdb.mk -->ignore this error
