# Disable SHA256 HW intrinsics on platforms where they're not available:
# 1. 32-bit ARM (armv7) - intrinsics only exist on ARM64
# 2. Windows ARM (MinGW cross-compilation) - crypto intrinsics not available in MinGW
# The LZMA SDK incorrectly enables USE_HW_SHA based on clang/gcc version checks,
# but vsha256hq_u32 and other SHA intrinsics may not be available.
# Force __clang_major__ and __GNUC__ to 0 for Sha256Opt.c to skip HW path.
