$ uname -m

$ ./truearch hello32 hello64 hellos
$ ./hellos
hello x86_64
$ setarch i386 ./hellos
Hello x86
$ setarch x86_64 ./hellos
hello x86_64
$ file hello32
hello: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), 
statically linked, for GNU/Linux 2.6.15, not stripped
$ file hello64
hello64: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically 
linked, for GNU/Linux 2.6.15, not stripped

While I didn't finish glibc hacks, I could use only statically linked 
binaries.

Rgds,
