[Distutils] How to make easy_install handle platlibs?

As PJE has mentioned, the intent is that the egg name should contain  
enough information to decide if that egg will work on your platform.   
For example, if it says "py2.5-win32" then you know it will work on  
your Python 2.5 on 32-bit Windows, and if it says "py2.5-macosx-10.3- 
ppc" then you know it will work on your PowerPC-based Mac with Python  
2.5.  This can be used for example by easy_install to get a directory  
listing of eggs and choose which one will work on the local platform  
based solely on its filename.

As PJE mentioned, it would be nice if this same technique worked on  
Linux.

However, it currently doesn't.  Eggs built on Linux are named  
something like py2.5-Linux-x86_64.  To know whether such an egg would  
actually work on your Linux system, you would also need to know  
whether the Python was compiled with UCS-2 or UCS-4 internal unicode  
representation, as well as what version of glibc you have.  Is there  
anything else that would need to be added into the egg name?
