strdup() is not portable.  The call to it in dl.m will lead to a memory
leak.  So that's not the right fix.

The right fix is probably to use MR_make_string() rather than
sprintf() and strdup().

The code using strdup() seems to have been committed already, but it
was never posted to mercury-developers.  Please don't do that!
