Comment 6 for bug 1099681

I see PS5.6.19(and PXC 5.6.19) is still affected.

$ bin/mysql_config
Usage: bin/mysql_config [OPTIONS]
Options:
        --cflags [-I/home/ttanaka/Percona-Server-5.6.19-rel67.0-618.Linux.x86_64/include -g -pipe -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -DPERCONA_INNODB_VERSION=rel67.0 -fPIC -g -fabi-version=2 -fno-omit-frame-pointer -fno-strict-aliasing -DMY_PTHREAD_FASTMUTEX=1]

        --variable=VAR VAR is one of:
                pkgincludedir [/home/ttanaka/Percona-Server-5.6.19-rel67.0-618.Linux.x86_64/include]
                pkglibdir [/home/ttanaka/Percona-Server-5.6.19-rel67.0-618.Linux.x86_64/lib/mysql]
                plugindir [/home/ttanaka/Percona-Server-5.6.19-rel67.0-618.Linux.x86_64/lib/mysql/plugin]

And I found "mysql_config --variable=pkglibdir" is wrong too.
