Cross Compilation: GNU/Linux Conventions


A cross-compiler is a compiler that creates executable code
                        for another processor

Building by yourself cross-code requires  three parameters
--build         (where is the code being built -- usually autodetected)
--host          (where will the code be hosted)
--target       (where will the code run)

Cross-compilation tools usually have a prefix in the filename
arm-linux-gcc  arm-buildroot-linux-gnueabi-gcc
m68k-linux-gcc lm32-elf-gcc

Building the kernel:
make CROSS_COMPILE=m68k-linux- ARCH=m68knommu
