奇怪，不知道是什么问题，在编gcc、binutils时不也要check size of long double 吗？

这有可能是binutils第一遍没有静态连接。
file /tools/bin/ld
如果报告动态连接，则要重新做binutils第一遍！

这个问题很常见。通常是由于某种原因binutils出问题造成的。

在第一遍binutils之后，
echo "main(){}" > dummy.c
cc dummy.c

如果出错，你的binutils就有问题了。检查路径的设置，检查/tools/bin等目录下的内容。必要时，
rm -rf /tools
然后重做binutils。
这个问题应该比较好处理的。
至于楼上说的静态连接，现在较新的LFS BOOKS已经不要求静态连接了。
