I am following the instructions
(https://www.openembedded.org/wiki/How_to_submit_a_patch_to_OpenEmbedded#Sending_via_a_pull_request)
under "Sending via a pull request".
I created a github fork (cloned it, created my commit and pushed it back to a
branch of my forked repo).
The problem I've run into is this:
```
bobhenz@hound:~/src/openembedded-core$ scripts/create-pull-request -u badger

NOTE: Assuming local branch HEAD, use -l to override.

Fix WantedBy processing
An empty string assignment to WantedBy should clear all prior WantedBy
settings. This matches behavior of the current systemd implementation.

lttng-tools: Disable on qemuriscv32
lttng-tools requires SYS_ppoll and SYS_pselect6 which are not supported on
riscv32. This has been confirmed by lttng-tools upstream.
https://github.com/lttng/lttng-tools/pull/162
It's also turned off for riscv32 in meta-riscv.

I will attach a new patch with a SoB. Can you explain the value of having me
sign off on my own PR? I guess I thought someone with more authority would be
signing off on the change...
Thanks for your guidance
