can't run some darwinlegacy binaries on MacOS Lion (again)

[Werner LEMBERG]

In August 2019 I wrote the following:

  Some of the new binaries fail to run on my MacOS 10.7.5 box:

    > pdftex --version
    dyld: Symbol not found: __ZSt9terminatev
      Referenced from: /usr/local/texlive/2019/bin/x86_64-darwinlegacy/pdftex
      Expected in: /usr/lib/libc++abi.dylib
     in /usr/local/texlive/2019/bin/x86_64-darwinlegacy/pdftex
    Trace/BPT trap: 5

  All affected binaries (at least `pdftex', `xetex', and `etex') show
  the same error.

I get the same again; the `pdftex` binary is dated June 30th, 2021;
the other ones are older.  Binaries from 2020 seem to work, BTW.
