Roland McGrath 8433646601 kconfig CROSS_COMPILE option

This adds CROSS_COMPILE as a kconfig string so you can store it in
.config.  Then you can use plain "make" in the configured kernel build
directory to do the right cross compilation without setting the
command-line or environment variable every time.

With this, you can set up different build directories for different kernel
configurations, whether native or cross-builds, and then use the simple:

	make -C /build/dir M=module-source-dir

idiom to build modules for any given target kernel, indicating which one
by nothing but the build directory chosen.

I tried a version that defaults the string with env="CROSS_COMPILE" so
that in a "make oldconfig" with CROSS_COMPILE in the environment you can
just hit return to store the way you're building it.  But the kconfig
prompt for strings doesn't give you any way to say you want an empty
string instead of the default, so I punted that.
