sha256sum Illegal instruction on musl amd64

[Henrique de Moraes Holschuh]

There is some data in:

https://www.intel.com/content/dam/develop/external/us/en/documents/intel-sha-extensions-white-paper.pdf

page 13.


If what the document above describes is what busybox is already doing on 
Intel, then it is time to find out the exact processor model that 
exposed the issue, hunt down its Specification Update documentation, and 
check for known errata, etc.

Do note the 16-byte alignment requirement for all buffers involved.
