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).

 # What we need:

 #  - the .config file

 # Parse the tools' paths configuration

 . "${CT_LIB_DIR}/paths.mk"

 # We'll need the stdout later, save it

 # Parse the common functions

 . "${CT_LIB_DIR}/scripts/functions"

 # Don't care about any log file

 exec >/dev/null

 # Parse the configuration file
