Merge #17569: build: Allow export of environ symbols and work around rv64 toolchain issue

eafd2593674b6890418a50eadf69425071b824e4 build: Add NX workaround for RV64 (Wladimir J. van der Laan)
f6e42256fe8900ed90f9644906b77f97e1600952 build: Allow export of environ symbols (Wladimir J. van der Laan)

Pull request description:

  This export was introduced in #17270 which added
  ```
  //! Necessary on some platforms
  extern char** environ;
  ```
  This should (finally) make the gitian build pass again (fix issue #17525.).

  Built on top of #17538 which should be merged first.
