This reverts commit 9f5a6f89d9
.
The reason for reverting this is:
* qemuwrapper has now a fallback method;
* when using multilib, calling qemu_target_binary from recipes would
always point to the qemu binary corresponding to the machine
architecture. Hence, postinstalls needing to use qemu would call the
wrong qemu user emulation binary;
