odoc required by cram depending on objs/byte

Expected Behavior

> dune runtest
> echo $?
0

Actual Behavior

> dune runtest
File ".foo.objs/byte/_unknown_", line 1, characters 0-0:
Error: Program odoc not found in the tree or in PATH
 (context: default)
Hint: opam install odoc

Reproduction

1. Create and check into an opam switch with only ocaml and dune
2. Create a file dune-project with (lang dune 3.18)
3. Create empty files foo.ml and foo.t
4. Create the following dune file:

(library (name foo))

(cram
 (deps
  (glob_files .foo.objs/byte/*)))

5. Run dune runtest

Specifications

• Dune 3.18.0
• OCaml 5.3.0
• Ubuntu 24.10

Reproduce the report with the shown dune-project, dune file, foo.ml, and foo.t files in a switch containing only OCaml and Dune. Run dune runtest and inspect how the cram dependency glob over .foo.objs/byte causes odoc to be required. Done means the reproduction no longer requires odoc or reports an unexplained missing program.
