<pre>
    There's a problem with `mpfr` and `libgmp` builds with bazel in libc, I could only compile libc by disabling `mpfr`, which in turn causes many tests to have `NO STATUS` or just fail.

The issue is known on Fedora Linux and Mac, reported to work on Debian and it was ok with `mpfr=system`. These are the tested platform so far.

How to get it to work is by:
```sh
bazel build --features=layering_check --config=generic_clang --@llvm-project//libc:mpfr=disable  @llvm-project//libc/...
```
indide `llvm-project/utils/bazel/`.
