commit b7fab6f285ff0ff3816b109a8c3131b6ded0b484
Author: edo <edo.rus at gmail.com>
Date:   Wed Oct 7 08:33:57 2020 +0300

    Allow cross-compilation with SIMD (x86_84) (#104)
    
    Replace runtime SIMD check with a compile-only test in case of
    cross-compilation.
    
    You can still use '--enable-simd=no' to build x86_64 code without
    SIMD instructions.
