[PATCH] D98861: [CMAKE] Fix cross-compilation build

[Vladislav Vinogradov via Phabricator via llvm-commits]

vinograd47 added a comment.

According to https://cmake.org/cmake/help/latest/command/try_run.html#behavior-when-cross-compiling:

If the `CMAKE_CROSSCOMPILING_EMULATOR` is not set, the `try_run` will create cache variables which must be filled by the user or by presetting them in some CMake script file to the values the executable would have produced if it had been run on its actual target platform. If the cache variables were not provided, CMake configuration fails with the following errors:

  CMake Error: TRY_RUN() invoked in cross-compiling mode, please set the following cache variables appropriately:
      errc_exit_code (advanced)
      errc_exit_code__TRYRUN_OUTPUT (advanced)
