The motivation is similar to (and implementation taken partly from)
#271288 --- some rebar3-compiled `.beam` files contain debug information
exposing references to `.hrl` files from the Erlang distribution it
was compiled with. This results in unnecessary store references.
See also #423588's change to Elixir's `generic-builder.nix` where the
same option is used when building to avoid the same issue.
