R14B02: "make install-docs" fails on Ubuntu 10.04 / 10.10 (using the source tar-ball)

[Boris Mühmer]

"make install-docs" fails on Ubuntu 10.04 / 10.10 systems using the
R14B02 source tar-ball (like in "R14B01").

The simple fix for "$ERL_TOP/Makefile.in" (or "$ERL_TOP/Makefile")
would be to change line 412 from
        $(ERL_TOP)/lib/erl_docgen/priv/bin/xref_mod_app.escript
-topdir $(ERL_TOP) -outfile $(ERL_TOP)/make/$(TARGET)/mod2app.xml
to
        $(ERL_TOP)/bin/escript
$(ERL_TOP)/lib/erl_docgen/priv/bin/xref_mod_app.escript -topdir
$(ERL_TOP) -outfile $(ERL_TOP)/make/$(TARGET)/mod2app.xml
