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).

4 Attached is a patch to add __attribute__ ((noinline)) to
7 Without this patch, the sec script that processed initfini.s removes a
8 part of inlined call_gmon_start, causing undefined label errors.
10 This patch solves the problem by forcing gcc not to inline
11 call_gmon_start with __attribute__ ((noinline)).
13 Tested by building for arm-none-lixux-gnueabi. OK to apply?
