[PATCH] pull $CROSS_COMPILE from env. if present

[PATCH] pull $CROSS_COMPILE from env. if present

[Jesse Barnes]

Simple patch to pull CROSS_COMPILE from the environment if it's
present, which makes it easier to compile the kernel with different
compiler versions and such.

Thanks,
Jesse

I like it, but...

If we do it for CROSS_COMPILE we should do it for ARCH as well.
Something like
ifeq ($(origin ARCH), undefined)
ARCH := $(SUBARCH)
endif

And then group ARCH and CROSS_COMPILE togeher in the Makefile, and
provide a few meaningful comments.
I will test it tomorrow if you do not beat me in it.

That's a good idea too, I used that awhile back when all my ia64
compiles were x86->ia64 cross-compiles...
