Can't bootstrap with clang >= 15 and gcc >= 13

[aaronmondal]

Description of the bug:

The abseil dependency used in upb is too old. Some symbols used by it no longer resolve.

Updating the gRPC dependencies would fix the issue.

What's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.

1. Install Clang 15 or 16 (edit, thanks to @davido: or GCC 13)
2. Try to bootstrap Bazel

Which operating system are you running Bazel on?

Gentoo X86_64 with clang profile

What is the output of bazel info release?

Tried at HEAD.

@aaronmondal I am seeing probably a different issue trying to build Bazel using gcc 13:

Ultimately, stdint.h was missing, in outdated abseil-cpp release, that was fixed upstream: [1] one year ago.

Not sure, if we need a separate issue for that?

My environment:

  $ gcc --version
gcc (SUSE Linux) 13.0.1 20230412 (experimental) [revision d339e9802f758e051b0a1ef6db732ff846cbf4e3]

@davido This is probably related "closely enough" to be a merged issue. The gRPC dependency (and related deps like upb and abseil) is ancient from an upstream/living at head perspective. I'll update the issue to include GCC.

IMO it's an issue in general that some dependencies are not updated frequently enough and the Bazel build tends to fail with recent compiler versions.

@aaronmondal thanks for the update.

I'm working on non intrusive abseil-cpp patch similar to #15168 and #15177, will upload PR in a moment.
