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).

     1 Original patch from gentoo: gentoo/src/patchsets/gcc/4.3.1/gentoo/00_all_gcc-4.1-alpha-mieee-default.patch
     2 Set the default behavior on alpha to use -mieee since the large majority of
     3 time we want this (bad/weird things can happen with packages built without
     4 -mieee).
     5 
     6 To satisfy those people who may not want -mieee forced on them all the time,
     7 we also provide -mno-ieee.
