[Libreoffice] buglet in 1ec7b6a4 (?)

[Tom Tromey]

Commit 1ec7b6a4 changed autogen.sh to create autogen.lastrun only if
some arguments were provided when invoking autogen.sh.

However, Makefile still has:

Makefile: autogen.lastrun configure.in ooo.lst.in set_soenv.in Makefile.in
        ./autogen.sh

This means that my build fails with:

$ make
make: *** No rule to make target `autogen.lastrun', needed by `Makefile'.  Stop.


I don't understand the need for 1ec7b6a4, so I didn't unpatch it.
Touching the file seems to be working ok as a workaround.
