1) Ensure "init_db.sql" and "test_db-sql" really get built.

2) Ensure the "*.def" files with NetWare linker options get distributed to the proper directories.


netware/BUILD/compile-netware-END:
  Ensure the "*.def" files are built for NetWare.
  
  This is a backport of a 5.1 fix which may not be needed in 5.0 but cannot do any harm:
  the general "link_sources" step might fall victim to a cleanup which would be fatal
  just for NetWare, because of problems in the ordering of SUBDIR entries.
netware/Makefile.am:
  1) The scripts "init_db.sql" and "test_db.sql" must be built in the NetWare phase.
  
  2) Use "basename", not sed.
