Android emulator for x86 does not run Android x86. (I don't know what
flavor of Android Google uses for x86 emulator but my guess that it's
Intel's Android-IA)
Android x86 does use Houdini for ARM to x86 translation. Houdini CAN (in
theory) be installed on x86 Android emulator, but this ain't easy (old
install methods for 4.x will not work).
Personally, I would just use a proper Android emulator like Genymotion,
Andex or Duos.
