Fix SSE 4.2 test

Browse Source 
When building with zig cc I get:

```
error: always_inline function '_mm_crc32_u32' requires target feature 'crc32', but would be inlined into function 'calc_crc32c' that is compiled without support for 'crc32'
    5 |       crc32c = (unsigned)_mm_crc32_u32(crc32c, *(unsigned*)text);
      |                          ^
1 error generated.
```

This PR adds -mcrc32, another option would be to use a different SSE4.2 op
