Hello Tincho et al.

I tried to build this package in buster but it failed:

--------------------------------------------------------------------------------

This is just how the build ends but not necessarily the relevant part.
I've put several build logs here:

https://people.debian.org/~sanvila/build-logs/golang-google-cloud/

I'm getting failure rates above 50% on n1-standard-1 machines from GCE,
but I leave the severity to you.

As usual, if you could not reproduce this easily I would gladly
provide ssh access to a machine where this happens very often.

If this is really a bug in one of the build-depends, please use reassign and affects,
so that this is still visible in the BTS web page for this package.

Thanks.
