[PATCH tegra-uboot-flasher] README: describe the CROSS_COMPILER variable

[Stephen Warren]

From: Stephen Warren <swarren-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>

The build script uses a cross-compiler. The variable CROSS_COMPILE can
be set to select one, or a default value will be assumed.

 This step creates the target binaries and supporting data files necessary to
 run the tegra-uboot-flasher script. You will always need to perform this step.
 
+You will need an ARM cross-compiler in order to compile U-Boot. This may be
+obtained from a distribution package, or be a custom-built toolchain. The
+environment variable CROSS_COMPILE should be set to select the compiler to
+use. CROSS_COMPILE should contain the common prefix of all the binaries in
+the cross-compiler, for example if gcc is arm-linux-gnueabi-gcc, then
+CROSS_COMPILE should be set to arm-linux-gnueabi-, or
+/path/to/arm-linux-gnueabi-. If this variable is not set, then the build
+script assumes a value of arm-linux-gnueabi-.

Applied, on github.
