[dvipdfmx] [PATCH] mingw: Don't copy libtool wrappers

[Karl Berry]

     install-exec-hook: install-bin-links
     if WIN32
    -	$(INSTALL_PROGRAM) call_xdvipdfmx$(EXEEXT) $(DESTDIR)$(bindir)/dvipdfm$(EXEEXT)

Any idea why this install-exec-hook exists in the first place?
I don't see it for other programs in the TL tree.
