Log Message:
make(1): fix aliasing problem in cached_stat from the previous commit

When the struct stat was used for both calling the actual stat and for
returning the result, no copying was needed.  This also had the side
effect that for the first call of cached_stat, the returned struct stat
included all the fields properly filled in, and on later calls, these
fields were all zeroed out.

These two variables are separate now, thus the fields need to be copied
explicitly.  There are no existing unit tests for this, but ./build.sh
failed reliably.
