<pre>If the filesystem path passed to writeArchive(..) contains a `%` it will fail
with "No such directory". I believe this is because sys::fs::createUniquePath()
gets called and replaces all `%` with a random number. It looks like
sys::fs::TempFile::create(Prefix + ".temp-archive-%%%%%%%.a") is common in the
LLVM tree, and `Prefix` is assumed to contain no `%` characters. Not exactly
sure how LLVM wants to resolve this, but my suggestion would be to take
direction from the `mktemp` API.
