Tentative fix in trunk by commit 12154.
Could you confirm it fixes the issue on your machine?

the current fix breaks builds not giving -build-dir;
as ocamlbuild tries to write in _build/_build/:

+ ocamlfind ocamlc -where > _build/ocamlc.where
/bin/sh: cannot create _build/ocamlc.where: Directory nonexistent
Command exited with code 2.
Compilation unsuccessful after building 1 target (0 cached) in 00:00:00.
Fatal error: exception Sys_error("_build/_digests: No such file or directory")

I fixed it with the attached one-liner in pr-5503.diff, which seems to work both with and without a build-dir specified.

Fixed in trunk (commit 12191).

Hopefully, this fix will work with all combinations (without -build, with -build relative, with -build absolute).

The fix is actually from Xavier, I'm the committer for technical reasons.
