  Log Message:
  -----------
  [libc] set -Wno-frame-address for thread.cpp (#77140)

The aarch64 code is using __builtin_return_address with a non-zero
parameter,
which generates the following warning:

llvm-project/libc/src/__support/threads/linux/thread.cpp:171:38: error:
calling '__builtin_frame_address' with a nonzero argument is unsafe
        [-Werror,-Wframe-address]
171 | return reinterpret_cast<uintptr_t>(__builtin_frame_address(1));
| ^~~~~~~~~~~~~~~~~~~~~~~~~~
    
Disable this diagnostic just for this file so that we can enable
-Werror.
    
Fixes: #77007
