To ease cross-compilation process, introduce a single variable with the prefix to all compiler-related executables.
Define CROSS_COMPILE=foo- if your compiler and binary utilities are foo-cc, foo-ar, foo-strip, etc. More specific variables override this, so if you set CC=gcc CROSS_COMPILE=ia64-linux-gnu- then the compiler will be 'gcc', not 'ia64-linux-gnu-gcc'.
