A dependency disjunction may select different package names on different
platforms. Preserve each platform's selection when generating a portable lock
directory.

$ mkrepo
$ add_mock_repo_if_needed

Define an implementation for each operating system:

$ mkpkg linux-impl <<'EOF'
> available: os = "linux"
> build: [
> ["mkdir" "-p" share "%{lib}%/%{name}%"]
> ["touch" "%{lib}%/%{name}%/META"]
> ]
> EOF

$ mkpkg macos-impl <<'EOF'
> available: os = "macos"
> build: [
> ["mkdir" "-p" share "%{lib}%/%{name}%"]
> ["touch" "%{lib}%/%{name}%/META"]
> ]
> EOF

The common package accepts either implementation:

$ mkpkg foo <<'EOF'
> depends: [ "linux-impl" | "macos-impl" ]
> build: [
> ["mkdir" "-p" share "%{lib}%/%{name}%"]
> ["touch" "%{lib}%/%{name}%/META"]
> ]
> EOF

$ make_portable_lockdirs_project
$ dune pkg lock
Solution for dune.lock

Dependencies common to all supported platforms:
- foo.0.0.1

Additionally, some packages will only be built on specific platforms.

arch = arm64; os = linux:
- linux-impl.0.0.1

arch = arm64; os = macos:
- macos-impl.0.0.1

arch = x86_64; os = linux:
- linux-impl.0.0.1

arch = x86_64; os = macos:
- macos-impl.0.0.1

The lock directory selects and builds only the appropriate implementation for
each platform:

$ DUNE_CONFIG__OS=linux DUNE_CONFIG__ARCH=arm64 DUNE_CONFIG__OS_FAMILY=debian DUNE_CONFIG__OS_DISTRIBUTION=ubuntu DUNE_CONFIG__OS_VERSION=24.11 dune build
$ ls $pkg_root/ | censor
foo.0.0.1-$DIGEST1
linux-impl.0.0.1-$DIGEST2

$ dune clean

$ DUNE_CONFIG__OS=macos DUNE_CONFIG__ARCH=x86_64 DUNE_CONFIG__OS_FAMILY=homebrew DUNE_CONFIG__OS_DISTRIBUTION=homebrew DUNE_CONFIG__OS_VERSION=15.3.1 dune build
$ ls $pkg_root/ | censor
foo.0.0.1-$DIGEST1
macos-impl.0.0.1-$DIGEST2
