- force neon on arm archs with neon since contrary to x86 simd
intrinsics it lacks runtime detection (BLAKE3_CFLAGS_NEON needs to be
defined to satisfy cmake logic, but are defined to empty value cause
our cflags handle it already)

+%description
+BLAKE3 is a cryptographic hash function that is:
+- Much faster than MD5, SHA-1, SHA-2, SHA-3, and BLAKE2.
+- Secure, unlike MD5 and SHA-1. And secure against length extension,
+ unlike SHA-2.
+- Highly parallelizable across any number of threads and SIMD lanes,
+ because it's a Merkle tree on the inside.
+- Capable of verified streaming and incremental updates, again because
+ it's a Merkle tree.
+- A PRF, MAC, KDF, and XOF, as well as a regular hash.
+- One algorithm with no variants, which is fast on x86-64 and also on
+ smaller architectures.
