[bitbake-devel] [PATCH 4/7] siggen: Use unique hashes for tasks

[Richard Purdie]

Now that runqueue optimises based on task hash, we need to ensure
tasks have unique hashes even in the simplest siggen mode. Use
the task name to calculate a unique hash.

This fixes runqueue tests when hash optimisations are added.
