CentOS ports: for c6_64, install 32bit libraries alongside.
Currently, there is no way of installing 32bit and 64bit CentOS libraries
alongside one another. With the ports framework's lacking the possibility of
building two (or more) packages from one port, the way to go about being able
to run both 32bit Linux apps (personal usecase: net-im/skype4) alongside 64bit
Linux apps (use whatever binary CentOS provides in some port we ship) is to
pull all 32bit libraries into the c6_64 ports.
