Failure introduced in 8cd4ecf

@mikhailramalho this is FYI, I'll submit this patch to restore bazel build.
You can monitor the state of the bazel build here https://buildkite.com/llvm-project/upstream-bazel

Weird that I didn't get any emails about this PR or the mention, it was only on the github notifications for some reason.

Anyway, I'll keep an eye out for my changes to cmake from now on, I didn't know we had to also support bazel... I never used it tbh.

I'm assuming PR #65383 also breaks compilation with bazel?

Bazel is considered a secondary build system for libc. We use the Bazel files at Google but they don't support all of the functions, features, and modes that the cmake files do.

You really only need to worry about Bazel when you're adding a new dependency to a file. Bazel is a lot more strict about includes than cmake.

Generally to test the bazel I use the following command from the folder llvm-project/utils/bazel:

bazel query @llvm-project//libc/... | xargs bazel test --config=generic_clang --test_output=errors --test_tag_filters=-nobuildkite --build_tag_filters=-nobuildkite --@llvm-project//libc:mpfr=system

I have that as part of my test script that I use to run all the tests before I land.
