Merge commit d0b9c2c56476 from llvm git (by David CARLIER):
[compiler-rt] Remove SHA2 interceptions for NetBSD/FreeBSD. (#110246)
To Fix #110215
Interceptors introduced with 18a7ebda99044473fdbce6376993714ff54e6690
This fixes undesirable runtime failures when using -fsanitize=-address
in combination with -lcrypto.
Direct commit to stable/14, because main already got this change as part
of the llvm-19 import.
Approved by: re (cperciva)
Reported by: Theo Buehler <tb@openbsd.org>
PR: 281685
(cherry picked from commit 4f1754bccef155c0fd24547ab3c872bd0f182224)
