[flac-dev] slow on apple silicon?

Ok, so the latest being slower on both builds at level 8 than the Released
1.3.4 makes sense with recent compression improvements. Thanks. I was using
level 8 for all tests.

As for the Neon optimizations, it seems that if I configure for Universal
binary ( -arch arm64 -arch x86_64),the neon optimizations are not on. If I
configure for just arm64, they are on:

  Configuration summary :

    FLAC version : ............................ 1.3.4

    Host CPU : ................................ aarch64
    Host Vendor : ............................. apple
    Host OS : ................................. darwin21.5.0

    Version string : reference libFLAC git-7e0a0e57 20220701

    Compiler is GCC : ......................... no
    Compiler is Clang : ....................... yes
    SSE optimizations : ....................... yes
    Neon optimizations : ...................... yes
    Asm optimizations : ....................... yes
    Ogg/FLAC support : ........................ no
    Stack protector  : ........................ no
    Fuzzing support (Clang only) : ............ no

However, make fails after this. If i configure for both architectures,
"make" succeeds, but no neon optimization.

Configure for just arm64 gives neon optimizations, but "make" gives a
bunch
of cputype errors:

What happens if you run 'make clean all' instead of just 'make'?
