We've currently got 18 architectures in QEMU, and thus 18 target-xxx folders in the root folder of the QEMU source tree. More architectures (e.g. RISC-V, AVR) are likely to be included soon, too, so the main folder of the QEMU sources slowly gets quite overcrowded with the target-xxx folders. To disburden the main folder a little bit, let's move the target-xxx folders into a dedicated target/ folder, so that target-xxx/ simply becomes target/xxx/ instead.
