Yes and no. Formally, libc.so is in a sort of reserved namespace (or
at least, -lc is), whereas there's nothing "reserved" about the name
ld-musl-$(ARCH).so.1. I agree this is fairly irrelevant however as
nobody else is going to use that library name unless they're trying to
break things.

Well the message should never happen unless ldconfig is processing the
directory containing libc.so, right? It doesn't happen for me on
Debian when I have musl's ld-musl-i386.so.1 in /lib and ldconfig
processes the default library path.
