* https://github.com/google/benchmark/commit/52613079824ac58d06c070aa9fbbb186a5859e2c
  is applied to fix cross compilation with MinGW headers
* https://github.com/google/benchmark/commit/439d6b1c2a6da5cb6adc4c4dfc555af235722396
  is applied to fix building with MinGW headers for ARM
* https://github.com/google/benchmark/commit/a9b31c51b1ee7ec7b31438c647123c2cbac5d956
  is applied to disable exceptions in Microsoft STL when exceptions are disabled
* Disabled CMake get_git_version as it is meaningless for this in-tree build,
  and hardcoded a null version
* https://github.com/google/benchmark/commit/4abdfbb802d1b514703223f5f852ce4a507d32d2
  is applied on top of v1.4.1 to add RISC-V timer support.

  are applied on top of the previous cherrypick to fix timestamp-related inline
  asm issues and 32-bit RISC-V build failures. The second cherrypicked commit
