Subject: Suppress UBSan warnings in the xoshiro implementation.
X-Git-Url: https://tinc-vpn.org/git/browse?p=tinc;a=commitdiff_plain;h=e32d4f3db3f1ed3eebe2e11d57512b60a6c02fa6

Suppress UBSan warnings in the xoshiro implementation.

Xoshiro relies on the well defined overflow behavior of unsigned
integer, but UBSan complains about it unless we force it to ignore it.
