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).

Original patch from Gentoo.

-= BEGIN original header =-

ARMV5 can use STRD and LDRD access instructions but these accesses need to be 

8 byte aligned. The dynamic linker's malloc needs to match this so structures

become 8 byte aligned to void unaligned accesses.
