    gnu: sbcl: Disable SB-SIMD module.
    
    SB-SIMD gets enabled only on x86_64 CPUs supporting AVX2 instructions,
    and some x86_64 CPUs don't.
    
    Fixes <https://issues.guix.gnu.org/56353>.
    Reported by Wensheng Xie <xiewensheng@hotmail.com>.
    
    * gnu/packages/lisp.scm (sbcl)[arguments]: Disable SB-SIMD in the 'build' 
and
      'build-doc' phases.
