complibs/ppl: fix 0.11-0.11.2 to compile with --disable-shared
PPL 0.11 (through 0.11.2) had a small bug where it still tried to build
and test its Java interface even when shared libraries are disabled.
Since that's exactly what ct-ng does, it explodes.
This is the patch from the PPL authors (see final link below).

5 gentoo/src/patchsets/binutils/2.19/66_all_binutils-2.18.50.0.2-warn-textrel.patch
7 textrels are bad for forcing copy-on-write (this affects everyone),
8 and for security/runtime code generation, this affects security ppl.
9 But in either case, it doesn't matter who needs textrels, it's
10 the very fact that they're needed at all.
