Subject: [PATCH] uutils-coreutils: symlink multicall aliases to fix closure
 size

Upstream commit fb76aba95b35 changed the default LN from `ln -sf` to
`ln -f`, so each utility alias is now a hardlink to the 14 MiB
multicall binary. NAR serialization does not preserve hardlinks, so
every alias is stored and downloaded as a full copy, taking the
closure from ~61 MiB to ~1.5 GiB.
