Make builds repeatable.
We have been using the time of compilation to determine the
version string. This CL will keep doing that if the git repo has
uncommitted changes, but if the repo is clean we'll just use the
author date of the last commit. This ensures that the same source
will produce bitwise-identical builds (assuming no toolchain
changes, of course).
BUG=chrome-os-partner:45616
BRANCH=none
TEST=manual
cd src/platform/ec
make buildall
mv build build.one
make buildall
md5sum build{,.one}/*/ec.bin | sort
Observe that successive builds produce identical binaries.
