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.
