#     powerpc/Makefile: Auto detect cross compiler
#     
#     If no cross compiler is specified, try to auto detect one.
#     
#     Look for various combinations, matching:
#       powerpc(64(le)?)?(-unknown)?-linux(-gnu)?-
#     
#     There are more possibilities, but the above is known to find a compiler
#     on Fedora and Ubuntu (which use linux-gnu-), and also detects the
#     kernel.org cross compilers (which use linux-).
#     
#     This allows cross compiling with simply:
#     
#      # Ubuntu
#      $ sudo apt install gcc-powerpc-linux-gnu
#      # Fedora
#      $ sudo dnf install gcc-powerpc64-linux-gnu
#     
#      $ make ARCH=powerpc defconfig
#      $ make ARCH=powerpc -j 4
#     
#     Inspired by arch/parisc/Makefile.
