 I'm afraid you have to provide config.log for me to debug why compile
 checks fail. configure.ac has the following logic:
 
   # s/x86_64/amd64/
   case "$target_or_host" in
     x86_64-*-*)
       have_x86=yes
       ;;
   esac
 
   AC_ARG_ENABLE(mmx, ...,, enable_mmx=$have_x86)
   AC_ARG_ENABLE(sse, ...,, enable_sse=$enable_mmx)
 
   if test "x$enable_mmx" = "xyes"; then
      AC_COMPILE_IFELSE(<mmx check>,
        if test "x$enable_sse" = "xyes"; then
            AC_COMPILE_IFELSE(<sse check>,, enable_sse=no)
        fi
      , enable_mmx=no)
   fi
 
 Also, there is no point in testing with OPTIMIZE turned OFF.
