Changing ebuilds for porting vboot_reference to u-boot

This CL is a first step toward porting vboot_reference to u-boot.

It installs necessary headers and cross-compiled static library of
vboot_reference to /build/${BOARD}/, and adds a compile-time dependency from
u-boot to vboot_reference.

Makefile of u-boot takes a new parameter VBOOT="${ROOT}/usr" pointing to a
verify boot implementation.
See: http://codereview.chromium.org/3515011

BUG=none
TEST=Run "emerge-${BOARD} u-boot" successfully

sysincludes.h should still be included.  That is, platforms should include all
of firmware/lib and firmware/include without modification.

biosincludes.h is what contains the platform-specific stuff.

Hi Randall,

I've added sysincludes.h.  Please take a look when you have time.

Done.  Thanks for the comments.

LGTM, thanks

LGTM, thank you.

I'm making the same change to the new chromeos-u-boot and chromeos-u-boot-next
ebuilds and will send out a review request shortly.  I'm also going to be
removing our sys-boot/u-boot ebuilds shortly.  Just a FYI.

Thanks,
