2.7.1 fails to bootstrap

[olafhering]

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"
....

Prepending a mkdir seems to be required, but bootstrap still fails:

Could you try master? There was a PR to fix the broken configure script.

[olafhering]

Works with commit 61d4703, thanks.

[rgrinberg]

Do you need us to release 2.7.2 with this fix?

[olafhering]

No need for a new release.

[rgrinberg]

Okay, well this is fixed in master then.
