issues building PPL 0.11.2

[Anthony Foiani]

Yann, all --

I ran into a variety of odd issues trying to build a toolchain on my
Fedora 14 (x86-64) system with the latest PPL release (0.11.2).

Here's the patch I'm currently using, and it seems to be working fine.
 If you really need me to, I can reformulate it as a proper mailed
patch with signed-off-by etc, but I feel it's minor enough to not
warrant it.  Whatever.  (Also, I still seem unable to really drive
'hg' properly, so my reformulating it would take me a few hours of
cloning and polishing, whee.)

Anyway, the issues I found:

1. a java test lib doesn't get a makefile rule if PPL is not built
shared. I first tried building shared, then eventually just build only
C and C++ interfaces.

2. PPL build was failing randomly, and it looked like it's not
entirely safe under parallel building; as such, I removed the parallel
build flag from the ppl.sh script.

I know that both of these issues should probably be pushed to upstream.

Thanks,
t.
