Merge make_all.sh to Makefile

By merging make_all.sh to Makefile, parallel make can be made faster.
Previously, if one does 'util/make_all.sh -j32', most of the time is
spent on waiting for linking. Now that we invoke sub-make, linking an
executable doesn't block the next board.

With '-j32', the new 'make buildall' takes about 7 seconds, while the
original 'util/make_all.sh' takes about 27 seconds.

BUG=None
TEST=make buildall -j32
BRANCH=None
