I wanted to apply your patch, but unfortunately, it fails to build for
me in host-grpc:

Could you have a look into this ?

Note that I did a number of fixes/cleanups in your patches, so it would
be nice if you could restart from the two patches I have pushed at
https://git.bootlin.com/users/thomas-petazzoni/buildroot/log/?h=grpc.

Thanks!
