2.7.1 fails to bootstrap #3774
Description
configure.ml expects a src/dune/setup.ml, which disappeared in 2.7.1
Long story:
So far the dependency chain looks like this: ocaml.rpm -> ocaml-dune -> rest of OCaml world.
The bootstrap of ocaml-dune.rpm looks like this:
ocaml configure.ml '--libdir=%{ocaml_standard_library}' '--mandir=%{_mandir}'
ocaml bootstrap.ml
rm -rfv '%{_tmppath}/%{name}-%{release}'
mkdir -vm 0700 '%{_tmppath}/%{name}-%{release}'
mkdir -vm 0700 '%{_tmppath}/%{name}-%{release}/bin'
test -x "$PWD/dune.exe"
ln -vs "$_" '%{_tmppath}/%{name}-%{release}/bin/dune'
export "PATH=%{_tmppath}/%{name}-%{release}/bin:$PATH"
....
