[yocto] DEVTOOL doesn't upgrade glibc as expected

[Dhanush K.S]

Hi,

I'm currently using Yocto Sumo 2.5 release with the glibc version 2.27 and
would like to upgrade it to v2.28.
Using the devtool upgrade glibc -V 2.28
-S 044c96f0d5595aeb0bb4e79355081c5a7f4faca5 doesn't work as expected.
In turn it creates the workspace/recipes/glibc_2.28.bb recipe with the
contents and SRC_URI of v2.27.

devtool upgrade glibc -S 044c96f0d5595aeb0bb4e79355081c5a7f4faca5

Resolve all conflicts manually, mark them as resolved with
"git add/rm <conflicted_files>", then run "git rebase --continue".
You can instead skip this commit: run "git rebase --skip".
To abort and get back to the state before "git rebase", run "git rebase
--abort".

You will need to resolve conflicts in order to complete the upgrade.

Need help with this one.
