With per-package enabled, this $(HOST_DIR) here will point to the
per-package host directory of host-meson instead of pointing to the
global host directory.

Here as well, but this one is not an issue: the per-package host
directory of host-meson will be rsync'ed into the global host directory
at the end of the build.

With per-package enabled, HOST_DIR, STAGING_DIR and TARGET_DIR have a
different value when building each package (they point to the current
package per-package directories) or when building stuff outside of a
package (they point to the global directories).

It's not so much sequential vs. parallel, but per-package directories
or not. Per-package directory can be used while doing a sequential
build.

Best regards,
