[libc] Bazel Builds not Working Properly

[bassiounix]

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:

bazel build --features=layering_check --config=generic_clang --@llvm-project//libc:mpfr=disable  @llvm-project//libc/...

inside llvm-project/utils/bazel/.
