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).

      Crosstool-NG relies on some external tools to be recent enough, namely:

        make = 3.81 (in some cases)

        m4 >= 1.4.12

        autoconf >= 2.63

        automake >= 1.10.2

        libtool >= 2.2.4

      If your system has older versions, we can build them for you,

      but you are strongly encouraged to update your system instead!
