$ file rjsupplicant
rjsupplicant: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.9, not stripped
$ uname -r
3.10-2-amd64
And it can be run on Linux amd64 successfully.
Though I don't have the source code of rjsupplicant, so I don't have further information.
`qemu-x86_64 -strace ./rjsupplicant -n eth0 -u USER -p PASS -d 1 -s internet` is attached as strace_qemu.log
The binary is available to download at http://ge.tt/6pgG1tw/v/0
