  "message": "Link mimalloc with --as-needed on Linux (#8211)\n\nThe mimalloc CMake code unconditionally adds libatomic to its link\ndependencies, but it\u0027s not actually needed on the modern systems\nthat we\u0027re building for. Adding the --as-needed flag causes the\nlinker to only link against the following libraries if they\nprovide symbols that are actually needed.\n\nFor static linking, we wrap mimalloc\u0027s injected dependencies in\n-Wl,--as-needed since they surface all the way up to the final\nlink line for each tool (I don\u0027t think it would hurt to just\nlink all the tools with --as-needed but this seemed cleaner).\nFor dynamic linking, it\u0027s sufficient to just make the libmimalloc.so\nlink with --as-needed.\n\nAs a drive-by cleanup, also make mimalloc a private dependency of\nlibbinaryen.\n\nFixes https://github.com/emscripten-core/emsdk/issues/928",
