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).

# Configuration file for sstrip tool facility

    help

      The sstrip utility, to maximise the striping of ELF binaries

      (executables and libraries).

      Buildroot version, forked off the original from ELFkickers.

      This one is somewhat maintained by the buildroot guys.

      Supports big-endian systems.

      NOTE! Please read.

        sstrip is now deprecated in crosstool-NG, as it has a few

        shortcomings. For example: it breaks for PPC targets, it

        does not build on non-ELF hosts (eg. mingw32, MacOS-X...).
