Put something like this into your ~/bin and forget. Or use Al's kmk
script: ftp://ftp.linux.org.uk/pub/people/viro/

$ cat ~/bin/cross-compile
#!/bin/sh

case "$#" in
0)
	echo "usage: cross-compile ARCH ..." >&2
	exit 1
	;;
esac

ARCH="$1"
shift
case $ARCH in
alpha|arm|m68k|s390|sh|sh64|sparc|sparc64|x86_64)
	CROSS_COMPILE=$ARCH-unknown-linux-gnu-
	;;
parisc)
	CROSS_COMPILE=hppa-unknown-linux-gnu-
	;;
ppc)
	CROSS_COMPILE=powerpc-unknown-linux-gnu-
	;;
ppc64)
	CROSS_COMPILE=powerpc64-unknown-linux-gnu-
	;;
*)
	echo "cross-compile: -ENOCROSSCOMPILER for $ARCH" >&2
	exit 1
	;;
esac
make ARCH=$ARCH CROSS_COMPILE=$CROSS_COMPILE "$@"
