Yes, there is.  do_some_task[depends] += "some-recipe:some_other_task".

DEPENDS is just a neat way of setting [depends] on do_configure to the list
of recipes in DEPENDS's do_populate_sysroot task.

The problem is that do_package_write doesn't exist: the task is
do_package_write_deb ..._ipk and ..._rpm.  Thus the single variable that
the classes and recipes write to, and the package classes do:

do_package_write_rpm[depends] += "${PACKAGE_WRITE_DEPS}"

Simples!  :)

IMHO, the current name is fine.  As the dependencies are added to
do_package_write, it's the most obvious name.
