For the record, just do:

export CROSS_COMPILE=xxx
make ARCH=arm tegra_defconfig
make ARCH=arm zImage

The only slightly difficult part is getting a CROSS_COMPILE value. Many
distros ship at least some ARM cross-compiler in their standard
package-set these days, and if not, you can download the Linaro
compilers or go to ftp://ftp.kernel.org/pub/tools/crosstool/index.html.
