Describe the bug

After upgrading nixpkgs to 22.05 from 21.11, trying to build a simple hello world C program, using the pkgsStatic.llvmPackages_11.stdenv or pkgsStatic.llvmPackages.stdenv or pkgsStatic.clangStdenv results in

/nix/store/fnw7g7s8z6wmaank060jpqppl0hiqbal-x86_64-unknown-linux-musl-binutils-2.38/bin/x86_64-unknown-linux-musl-ld: cannot find -lgcc_eh: No such file or directory
clang-11: error: linker command failed with exit code 1 (use -v to see invocation)

Steps To Reproduce

Steps to reproduce the behavior:

1. flake.nix:

   {
     inputs.nixpkgs.url = "nixpkgs/nixos-22.05";
   
     outputs = { nixpkgs, ... }:
       let
         system = "x86_64-linux";
         pkgs = import nixpkgs { inherit system; };
         pkgsStatic = pkgs.pkgsStatic;
         stdenvStatic = pkgsStatic.llvmPackages.stdenv;
         # also tried:
         # stdenvStatic = pkgsStatic.clangStdenv;
       in
       {
         packages.${system}.default = stdenvStatic.mkDerivation {
           name = "hello";
           src = ./.;
           unpackPhase = ''
             cat > hello.c <<"EOF"
             #include <stdio.h>
             int main() {
               printf("hello, world\n");
             }
             EOF
           '';
           buildPhase = "$CC -o hello hello.c";
           installPhase = "install -D -t $out/bin hello";
         };
       };
   }

2. nix build .

   $ nix build .
   error: builder for '/nix/store/pgk2n1vcmy4gjkqycbqs1wblmjmwhwpz-hello-x86_64-unknown-linux-musl.drv' failed with exit code 1;

          For full logs, run 'nix log /nix/store/pgk2n1vcmy4gjkqycbqs1wblmjmwhwpz-hello-x86_64-unknown-linux-musl.drv'.

Expected behavior

I am able to build a static executable, based on musl, with clang.

Additional context

It seems like the gcc_eh.a library is indeed missing:

ls /nix/store/d41dvnv1rir038hxx8k8xf57icrfz7l4-x86_64-unknown-linux-musl-stage-final-gcc-11.3.0/lib64/gcc/x86_64-unknown-linux-musl/11.3.0/*.a
   libgcc.a    libgcov.a

Removing the -lgcc_eh option from the linker flags and manually running the resulting command produces a valid executable. (but I suppose this only works since I am not using exceptions ?)
