Add special variable for MultiArch-unaware components

Browse Source 
Some components are not yet MultiArch-aware and installs to either
lib/ (Debian) or lib64/ (RHEL) on 64-bit platforms. If we need to
interface with these components, then it is nice to have such a
variable set together with the regular detection code.
