build_oai: don't redirect compilations to a file

Redirecting to a file has the problem that it is difficult in the CI to
recover these files. Furthermore, at least with ninja, when running
build_oai interactively, the build output will only take some lines
(because ninja rewrites lines), so the change should not be that big to
users.

One CI function would print the entire output from build_oai to the
console. Since that output might be long now, do not do this. The file
is archived, anyway.
