4349051dd47416b8daad98f5fb87dea9b8e370d0 build: reorder cxxflags in intrinsic checks (fanquake)

Pull request description:

  Let the user have the final say in regards to using intrinsics.

  As outlined in https://github.com/bitcoin/bitcoin/issues/13758, on master:
   ```bash
  ./autogen.sh
  ./configure CXXFLAGS="-mno-avx -mno-avx2"
  …
  checking whether C++ compiler accepts -mavx -mavx2... yes
  checking for AVX2 intrinsics... yes
  …
  make
  …
   crypto/sha256_avx2.cpp: In function ‘__m256i sha256d64_avx2::{anonymous}::K(uint32_t)’:

  ```

  with this branch:
  ```bash
  ./autogen.sh
  ./configure CXXFLAGS="-mno-avx -mno-avx2"
  …
  checking whether C++ compiler accepts -mavx -mavx2... yes
  checking for AVX2 intrinsics... no
  …
  make check
  ```

  Fixes: #13758
  Alternative to #13789, which should work for all compilers.
