Indeed. It will be some time before this is the only issue preventing
lld from being a viable linker to include with the FreeBSD base
system. Eventually we'll determine that there's enough demand for -r
in lld, or that we should look for a different way to approach this in
FreeBSD.

The linker set functionality is very convenient, but if I had to
implement it without -r I imagine I'd generate a file at build time
that references each of the individual modules, and #include it from
the C source.
