[#3561 @rjbou - fix #3523 #3548]
* Lint E57: A description or a synopsis must be present and non empty.
[#3581 @rjbou - fix ocaml/opam-repository#12729]
* Lint W58: Advise to use `with-test` and `with-doc` variables if `test`
and `doc` are present. [#3591 @rjbou - fix #3580 ocaml/opam-repository#12729]

* Not having wget or curl is now only a hard-error if src_ext/archives doesn't
contain the archives (i.e. if make -C src_ext cache-archives has not been run)
which means that this should no longer be a requirement for building with the
"full" tarball. [#3572 @dra27 - fix #3551]
* C++ test for MCCS is now moved to the correct place and the message as to
whether the solver will be build should work correctly with --disable-checks.
Note that not having a C++ compiler is not considered an error if
--disable-checks is specified because configure is permitted to believe that
the MCCS library exists even if it couldn't detect it. [#3572 @dra27]
