I tried testing this in a VM with 32-bit Debian. It fixes the build
problems, but t5000 still fails.
I think you need to add the prereq to one more test:
diff --git a/t/t5000-tar-tree.sh b/t/t5000-tar-tree.sh
index 699355b..80b2387 100755
--- a/t/t5000-tar-tree.sh

We shouldn't be accessing the blob in update-index, but I think "git
commit" does so for the diff (and then after seeing the size says
"whoops, that's binary", but even the size check fails on 32-bit
systems).
So another solution would be to use "commit -q" at the end of that test.
I don't think there's much point, though; it's just setting up a state
for other tests that need LONG_IS_64BIT.
As an aside, it is inadvertently testing that our diff code does not
bother to read the whole blob in such a case. Which maybe argues for
using "commit -q", just because that is not a thing we are intending to
test here.
