[Nmh-workers] Dodgy $LINK in generated Makefile

[Lyndon Nerenberg]

The autogoo-generated Makefile is linking binaries with:

  LINK = $(CCLD) $(AM_CFLAGS) $(CFLAGS) $(AM_LDFLAGS) $(LDFLAGS) -o $@

Neither of $AM_CFLAGS or $CFLAGS should be in there.  I don't have enough 
autotools fu to know how to fix this ...
