gcc 16.1.1+r346 broke clang 22.1.8-1

Hi all. I don't have a GitLab account to open a bug report.
gcc 16.1.1+r346+g4e03491b401d-1 broke clang 22.1.8-1
I think this is related: Move some libgcc related files to $_libdir

Steps to reproduce:
1. Try compiling lib32-mesa with clang

ecking for function "__builtin_ia32_clflushopt" : NO 
Checking if "GCC atomic builtins" compiles: YES 
Checking if "GCC atomic builtins required -latomic" links: NO 

../mesa-26.1.4/meson.build:1493:20: ERROR: C shared or static library 'atomic' not found

Note: works with gcc 16.1.1+r346+g4e03491b401d-1
2. Try compiling lib32-llvm  with clang

- The C compiler identification is Clang 22.1.8
-- The CXX compiler identification is Clang 22.1.8
-- The ASM compiler identification is Clang with GNU-like command-line
-- Found assembler: /usr/bin/clang
-- Detecting C compiler ABI info
-- Detecting C compiler ABI info - failed
-- Check for working C compiler: /usr/bin/clang
-- Check for working C compiler: /usr/bin/clang - broken
CMake Error at /usr/share/cmake/Modules/CMakeTestCCompiler.cmake:67 (message):
  The C compiler

    "/usr/bin/clang"

  is not able to compile a simple test program.

  It fails with the following output:
