lld_14 with clang_14 cannot use libstdc++.so.6: cannot open shared object file: No such file or directory #215260
Description
Describe the bug
llvm-tblgen can not find libstdc++.so.6.
FAILED: include/llvm/IR/Attributes.inc <llvm-project>/llvm-project/build/include/llvm/IR/Attributes.inc
cd <llvm-project>/llvm-project/build && <llvm-project>/llvm-project/build/bin/llvm-tblgen -gen-attrs -I <llvm-project>/llvm-project/llvm/include/llvm/IR -I<llvm-project>/llvm-project/build/include -I<llvm-project>/llvm-project/llvm/include <llvm-project>/llvm-project/llvm/include/llvm/IR/Attributes.td --write-if-changed -o include/llvm/IR/Attributes.inc -d include/llvm/IR/Attributes.inc.d
<llvm-project>/llvm-project/build/bin/llvm-tblgen: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory
Confirmed that g++/clang++ can generate correct minimal C++ binary (with libstdc++), but recently llvm-tblgen breaks.
Steps To Reproduce
Steps to reproduce the behavior:
- Use recent nixpkgs/nixos-unstable
- build the llvm-project
