Separate utility build for build and host utils
Build is the system doing the build (e.g. 64-bit linux) and host is the
target platform on top of the ec (e.g. 32-bit Chromium OS).
Necessary to get ectool properly compiling for Chromium OS.
Signed-off-by: Randall Spangler <rspangler@chromium.org>
BUG=none
TEST=make && file build/bds/util/ectool; ectool should be a 32-bit binary
