Old versions of libtool for OpenBSD insist on adding the `-t` flag to
ranlib, which updates the timestamp. llvm-ranlib does not support `-t`
and as no plans to do so [1], since it makes builds less reproducable.
OpenBSD upstream deals with this by patching ranlib to ignore the `-t`
flag [2].
Instead of writing patches for all LLVM versions or re-running `autoreconf`
on all packages that use libtool, we can wrap ranlib to ignore the flag.
