Re: [PATCH v3] llvm/mesa/rust: simplify llvm-config handling

[Deepesh Varatharajan <Deepesh.Varatharajan@windriver.com>]

Hi Dmitry,

Yogesh has already posted a potential fix for this issue, and it is 
currently available in Mathieu's master-next branch.
https://git.openembedded.org/openembedded-core-contrib/commit/?h=mathieu/master-next&id=2e8ada1cb07d6dce8a0894b427b18b2bc585a2c8

I tested it locally, and it appears to resolve the issue. Could you 
please give it a try on your side and let us know if it
fixes the problem for you?

Regards,
Deepesh
