bazel build failure: error: ambiguating new declaration of 'long int gettid()'

[vbatts]

Description of the problem / feature request:

https://copr.fedorainfracloud.org/coprs/vbatts/bazel/ || https://github.com/vbatts/copr-build-bazel

This build issue has been happening since around v0.25.1, but since this is on fedora rawhide which is their rolling development head, this could be due to a latest gcc, glibc, etc

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

build fedora rawhide rpm
docker run -it fedora:rawhide

What operating system are you running Bazel on?

fedora rawhide x86_64

What's the output of bazel info release?

n/a

If bazel info release returns "development version" or "(@non-git)", tell us how you built Bazel.

n/a

What's the output of git remote get-url origin ; git rev-parse master ; git rev-parse HEAD ?

this is from v0.27.0 release zip archive

[benjaminp]

This is a gRPC issue: grpc/grpc#18950

[vbatts]

I'm carrying your patch for now, @benjaminp, so that I can build on fedora rawhide

[vbatts]

success: https://copr.fedorainfracloud.org/coprs/vbatts/bazel/build/943012/

[vbatts]

closing, as bazel-2 has rebased to include upstream grpc fix
