Ubuntu Jammy can’t compile fuzz tests with libc++? #24289

   Steps to reproduce on a fresh Ubuntu install:

   0export DEBIAN_FRONTEND=noninteractive && apt update && apt install curl wget htop git vim ccache -y && git clone https://github.com/bitcoin/bitcoin.git bitcoin-core && cd bitcoin-core && apt install build-essential libtool autotools-dev automake pkg-config bsdmainutils python3-zmq     libevent-dev libboost-system-dev libboost-test-dev  clang llvm libc++-dev libc++abi-dev  -y   &&  ./autogen.sh && ./configure CC=clang CXX='clang++ -stdlib=libc++'   --enable-fuzz --with-sanitizers=fuzzer && make -j$(nproc)
   

   Ubuntu Focal: (Passes) Ubuntu Jammy: (fails)

   0checking whether the linker accepts -fsanitize=fuzzer... no
   1configure: error: linker did not accept requested flags, you are missing required libraries

   Minimized test case:

   0cat /tmp/a.cpp 
   1#include <stdint.h>
   2#include <stddef.h>
   3extern "C" int LLVMFuzzerTestOneInput(const uint8_t *, size_t ) {   return 0; }
   

   0clang++ -fsanitize=fuzzer /tmp/a.cpp # (passes)
   

   0clang++ -stdlib=libc++ -fsanitize=fuzzer /tmp/a.cpp # (fails)
