[tex4ht] java modules

[Vincent Belaïche]

Here is a fix for the problem that you observed.
I did not have the same thing. Probably my cp version is not the same
and does not cause an error when the wildcard expansion is empty.
That is strange because I tried some "cd /tmp ; mkdir toto; cp
I-dont-exist/* toto" in sh and it did not work.
I am a bit puzzled why I did not observed the same error.
Actually the ./xtpipes.dir/lib directory does not exist because in the
whole tex script nothing is written to the nor aren't there any mkdir
thereof. So my fix is that I abruptly removed the faulty instruction.

Concerning the java compilation, maybe it would have been more
appropriate to disable it in the .tex by default unless do_java is
defined and keep it enabled always in the makefile (or maybe do_java
could switch where we want it to be made, in both places, only in
makefile, only in .tex files).
That would be easy to do through the texh4t-dir.tex that could contain
a switch passed from the makefile.
