Sorry, but your patch looks completely pointless.

I don't see what it has to do with multiarch support.
For example, x86_64 supports 3 personalities (x86_64, i386 and x32),
so it may require 3 different implementations, but your scheme does not
allow 3 different implementations to be linked into a single executable.

Are you going to make 25 clones of every personality-specific function?
I suppose there are hundreds of them.

I agree all personality specific code needs to be isolated, but it
certainly shouldn't be cloned for each architecture.

First of all, please have a look at
