test defs: fix 'javac' requirement for older JDK versions
- The parallel-tests driver now does not produce erroneous results
with Tru64/OSF 5.1 sh upon unreadable log files any more.
- - The makedepend depmode now works better with VPATH builds.
+ - The makedepend and hp depmodes now works better with VPATH builds.
- Java sources specified with check_JAVA are not compiled anymore upon
"make all", but only upon "make check".

## Some versions of gcc put a space before the `:'. On the theory
## that the space means something, we add a space to the output as
-## well.
+## well. hp depmode also adds that space, but also prefixes the VPATH
+## to the object. Take care to not repeat it in the output.
## Some versions of the HPUX 10.20 sed can't process this invocation
## correctly. Breaking it into two sed invocations is a workaround.

+# hp depmode should work with GNU make in VPATH mode (bug similar to
+# depcomp9.test).
+
+# Here's the bug: hp depmode will prefix VPATH to the object file name,
+# thus the second gmake will invoke depcomp with object='../../src/foo.o',
+# causing errors such as:
+# cpp: "", line 0: error 4066: Cannot create "../../gllib/.deps/nonblocking.TPo" file for "-M../../gllib/.deps/nonblocking.TPo" option. (No such file or dir
