'cross_compiling' is defined by the top Makefile and available for
arch Makefiles to check whether it is a cross build or not. A good
thing is the variable name 'cross_compiling' is self-documenting.

This is a simple replacement for m68k, mips, sh, for which $(ARCH)
and $(SRCARCH) always match.

No functional change is intended for xtensa, either.

This is rather a fix for parisc because arch/parisc/Makefile defines
UTS_MATCHINE depending on CONFIG_64BIT, therefore cc-cross-prefix
is not working in Kconfig time.
