Introduce an API to get target-specific information
from our current binary names (considered legacy as
of today).

At this point, get endianness and target_long_bits,
just enough to build qemu-system-microblaze (default
to big endian) and its little-endian symlink:

 $ make qemu-system-microblaze{,el}

 $ ./qemu-system-microblaze -M help
 Supported machines are:
 none                 empty machine
 petalogix-ml605      PetaLogix linux refdesign for xilinx ml605 (big endian) (deprecated)
 petalogix-s3adsp1800 PetaLogix linux refdesign for xilinx Spartan 3ADSP1800 (big endian) (default)
 xlnx-zynqmp-pmu      Xilinx ZynqMP PMU machine (big endian) (deprecated)

 $ ./qemu-system-microblazeel -M help
 Supported machines are:
 none                 empty machine
 petalogix-ml605      PetaLogix linux refdesign for xilinx ml605 (big endian) (deprecated)
