[Tarantool-patches] [PATCH 04/10] crc32: disable align sanitizer

[Vladislav Shpilevoy]

There is some assembly working with a byte array like with an
array of unsigned long values. Better allow it to continue
working like that with disabled sanitizer, than accidentally
break or slow down something here.

Part of #4609
---
I am sure there is a way to fix it instead of muting, but I don't
know how. Probably there is someone, who understands what is
written in this assembly code, and can help.
