Subject: musl vs. Debian policy

I started writing a short explanation of the musl installation for packagers, and realized that there's one area that's inconvenient:
$syslib/ld-musl-*.so.1 is a symlink to

Debian policy requires that any public libraries have a version number. 
Specifically, Debian Policy 8.2 
If your package contains files whose names do not change with each change in the library shared object version, you must not put them in the shared library package. Otherwise, several versions of the shared library cannot be installed at the same time without filename clashes, making upgrades and transitions unnecessarily difficult.

The apparent solution to this is to ship only the dynamic linker, since this is all we need (the dependency on is disregarded when it comes to running dynamically linked programs).  But currently, actually doing this would be somewhat of a hack.

Is there any prospect of installing lib/ straight to ${LDSO_PATHNAME} ? I'm thinking it could be done via something like:

install-ldso: $(DESTDIR)$(LDSO_PATHNAME)

        install -D -m 755 $< $@

I realize it would also be necessary to adjust the rules for installing, however. If the change is welcome, I could prepare a patch.
