mpg123: update to 1.27.0
Enable cpu-specific optimizations.

I didn't test arm and ppc.

`./configure --help` says:
```
  --with-cpu=generic[_fpu]      Use generic processor code with floating point arithmetic
  --with-cpu=generic_float      Plain alias to generic_fpu now... float output is a normal runtime option!
  --with-cpu=generic_nofpu      Use generic processor code with fixed point arithmetic (p.ex. ARM)
  --with-cpu=generic_dither     Use generic processor code with floating point arithmetic and dithering for 1to1 16bit decoding.
  --with-cpu=i386[_fpu]         Use code optimized for i386 processors with floating point arithmetic
  --with-cpu=i386_nofpu         Use code optimized for i386 processors with fixed point arithmetic
  --with-cpu=i486         Use code optimized for i486 processors (only usable alone!)
  --with-cpu=i586         Use code optimized for i586 processors
  --with-cpu=i586_dither  Use code optimized for i586 processors with dithering (noise shaping), adds 256K to binary size
  --with-cpu=3dnow         Use code optimized for 3DNow processors
  --with-cpu=3dnow_vintage Use code optimized for older 3DNow processors (K6 family)
  --with-cpu=3dnowext      Use code optimized for 3DNowExt processors (K6-3+, Athlon)
  --with-cpu=3dnowext_alone     Really only 3DNowExt decoder, without 3DNow fallback for flexible rate
  --with-cpu=3dnow_vintage       Use code optimized for older extended 3DNow processors (like K6-III+)
  --with-cpu=mmx          Use code optimized for MMX processors
  --with-cpu=mmx_alone          Really only MMX decoder, without i586 fallback for flexible rate
  --with-cpu=sse          Use code optimized for SSE processors
  --with-cpu=sse_vintage  Use code optimized for older SSE processors (plain C DCT36)
  --with-cpu=sse_alone          Really only SSE decoder, without i586 fallback for flexible rate
  --with-cpu=avx          Use code optimized for x86-64 with AVX processors
  --with-cpu=x86          Pack all x86 opts into one binary (excluding i486, including dither)
  --with-cpu=x86-64       Use code optimized for x86-64 processors (AMD64 and Intel64, including AVX and dithered generic)
  --with-cpu=altivec      Use code optimized for Altivec processors (PowerPC G4 and G5)
  --with-cpu=ppc_nofpu    Use code optimized for PowerPC processors with fixed point arithmetic
  --with-cpu=neon         Use code optimized for ARM NEON SIMD engine (Cortex-A series)
  --with-cpu=arm_fpu      Pack neon and generic[_dither] decoders, for ARM processors with FPU and/or NEON
  --with-cpu=arm_nofpu    Use code optimized for ARM processors with fixed point arithmetic
  --with-cpu=neon64       Use code optimized for AArch64 NEON SIMD engine
  --with-cpu=aarch64      Pack neon64 and generic[_dither] decoders, for 64bit ARM processors
