[PULL 3/7] configure: Add -Werror to avx2, avx512 tests |

From: Richard Henderson <richard.henderson@linaro.org>
When using clang, we get
ERROR: configure test passed without -Werror but failed with -Werror.
This is probably a bug in the configure script. The failing command
will be at the bottom of config.log.
You can run configure with --disable-werror to bypass this check.
What we really want from these two tests is whether the
entire code sequence is supported, including pragmas.
Adding -Werror makes the test properly fail for clang.
