No.
On a redhat or suse linux - probably that Linux distros with most 
installations on this blue marble - 32 bit i386 libs are in 'lib' and emt64 
libs in 'lib64'.
Well debian does it 'right' from that point of view, but ....

I could not find such a thing.
Can you give me a more concrete hint?

But yes, for most of the platforms (I believe AIX will still fall through), 
such a path suffix that can be globally configurable would help much.

Ok, the problem with AIX: They have archive files that can even einclude 
object or shared object files for different abis. The linker cares for 
selecting the correct ones. At least we observed that with some libraries ...
Strange, but the real existing world ...
