tools/ppl: fix automake error due to use of obsolete directory name

I recently experienced this:

configure.ac:1101: the top level
interfaces/Prolog/Ciao/Makefile.am:168: `pkglibdir' is not a legitimate directory for `DATA'
interfaces/Prolog/GNU/Makefile.am:167: `pkglibdir' is not a legitimate directory for `DATA'
interfaces/Prolog/SICStus/Makefile.am:71: `pkglibdir' is not a legitimate directory for `DATA'
interfaces/Prolog/SWI/Makefile.am:187: `pkglibdir' is not a legitimate directory for `DATA'
interfaces/Prolog/XSB/Makefile.am:186: `pkglibdir' is not a legitimate directory for `DATA'
interfaces/Prolog/YAP/Makefile.am:176: `pkglibdir' is not a legitimate directory for `DATA'
make[4]: *** [Makefile.in] Error 1

Found this on google:
http://bugs.mysql.com/bug.php?id=63898

And used this to fix it:
fgrep -rlZ pkglib_DATA --include Makefile.am . | xargs -0 sed -i 's/pkglib_DATA/pkgdata_DATA/g'
