They end up shared on FreeBSD (via packaging) as well, though I'm not the
package maintainer for that one and didn't fully track down exactly where
that happens. (The default INSTALL_LIB specifies a file mode to use, but
it was not entirely clear to me that we actually honor INSTALL_LIB just
from a `git grep`.)
