Most current "64 bit" Linux distributions are not pure 64-bit but contain both 
32 and 64 bit libraries.  In other words, they are multi-arch.

This does not change the fact that it is a bodge.

I am running a pure 64 bit Debian system.  The kernel, libraries and userland 
are all compiled as 64-bit software, and that's the way it should be.  Legacy 
32-bit software is *always* going to hold you back.  Whatever you want to get 
working, just re-compile it in 64-bit mode -- it's as simple as make 
clean, ./configure, make, su, make install.

Binary compatibility is irrelevant at best  {every Linux machine already has a 
compiler installed}  and harmful at worst  {Windows has wide-scale binary 
compatibility -- and rampant malware}.  All that matters is _source_ 
compatibility:  that the same source code will compile cleanly on a range of 
different architectures.  Thanks to the excellent work done by the GNU 
project in developing their compiler suite and automated configuration / 
building tools, source compatibility is already a reality.  And processors 
are fast enough now that there is no time saved in using precompiled
