Executables built with (e.g.) g++ -static still show a runtime dependency
on /lib/ld-musl-x86_64.so.1. My recollection from the past was that it was
possible to achieve a completely static a.out. Is there a way?

It is not possible to run PIE binary without dynamic linker - it needs 
to do relocations at runtime.

I don't know if it's possible to bundle dynamic linker with your binary.

Thank you.

Is it possible to turn off the PIE?

I may be able to ship the linker along with, but I just want to understand
the options.

I wouldn't recommend that. As far as I understand one should be able to
compile static PIE binaries, at least with gcc [1]. See also the
documentation [2] for `--static-pie` (ctrl-f static-pie).
