commit a643559150fa6fe3842beaabc4b20f4edb42a18a
Author: Herbert Valerio Riedel <hvr at gnu.org>

    Copy GHC's config.guess/sub over libffi's versions
    
    This should address #9924 as GHC's config.guess/sub versions need to be
    up to date anyway.
    
    (cherry picked from commit 9ae78b0ac20199982b994122889a04c6124e01b2)
