[bug#59487] [PATCH 1/2] build-system/dune: Automatically deduce test-target in most cases.

[pukkamustard]

Hi! Sorry, I missed these patches and only found them after realizing
that your Mirage patches require these.

I'm having trouble applying the second patch (of V2), maybe there have
been changes that cause conflicts? Could you rebase on master or just
resend the V2 patches to 59487@debbugs.gnu.org? Maybe with a short
comment if and how they address Julien's suggestion?
